MSSL WH SYSTEM Product Engineer Interview Questions and Answers

Round: Case Study Interview
Experience: I started off saying that the problem statement looks like it’s a Go/NoGo decision we have to help make, so first we should establish the exact objective against which we would measure our decision. Once the objective is clear, we would need to establish our current performance against the objective, what is the target level we wish to achieve on that particular objective and then evaluate if the new terminal would help us achieve that or not. But before that I would like to clarify about exactly what is meant by a terminal here.
JC: Heathrow is one of the busiest airports and already has 4 different passenger terminals, now they want to add a 5th. A terminal provides the usual services like Bays for Boarding & disembarking, Check-In, Security, Lounges & shopping areas etc.
Me: Great, do we also have to look at the financial and operational viability of the terminal or that is not a concern.
JC: for the purpose of discussion let’s ignore that, those would not be the constraints.
Me: Ok, so maybe we should the start looking at what the administrations core objective is for the new terminal. Why does it want to come up with a 5th terminal?
JC: Why don’t you tell me what those objectives could be?
Me: Well there could be many (started jotting down options in parallel as I spoke): 1) increase the #Passengers served per year, 2) Reduce Flight Congestion if any, 3) Reduce the Time spent by flights on the airport, 4) Increase the airports revenue sources. Am I missing any other?
JC: No I think you have mentioned the major ones, let’s briefly talk about each of these. What do you mean by the revenue sources?
Me: Then we had a brief discussion about revenues from shopping areas etc. Then we came to Flight congestion – primary metric there was time spent in air waiting for permission to land etc. Then we came to #Passengers served per year which is more of a demand metric and effectively dependent on the number of flights we can serve per day. We also discussed Time spent by flights on the airport and split that into further two types – flight landing and takeoff time and turnaround at the gates. At the end of this brief digression it emerged that if Time spent by Flights on airport can go down, #Flights can go up and so can #passengers, at the same time congestion can go down as well. Me: (summarizing) So is it fair to say that the objective of building the 5thterminal is to achieve a higher capacity at the airport and our problem definition is to evaluate that claim?
JC: Yes, if you wish to frame it so - effectively our problem definition is if the 5th terminal adds to the capacity of the System? Me: Good just give me a minute to put my thoughts in place as to how we can go about evaluating this?
JC: Sure..
Me: Ok as I mentioned, what we need to decide what is the exact metric used for measuring Capacity? Then what is the current value of airport for that metric? Then what impact would the new terminal on the level of the metric? That should lead us to an answer.
JC: Ok, so what do you want to know
Me: How do airports measure their capacity?
JC: Two commonly used metrics are ATM – Air Traffic Movements, and MPPA – Million Passengers Per Annum. For our discussion lets focus on ATM.
Me: So just to clarify ATM refers to a single air traffic movement, therefore the turnaround of one flight i.e. landing and take off would count as one or two ATMs?
JC: Two Me: Ok, so do we know what is the current ATM?
JC: How would you find that out?
Me: well the annual ATM would be average Flights per day * 365 * 2 JC: Right lets keep the analysis to per day Me: Ok so what’s the current #daily flights?
JC: Am not sure why that is relevant here for answering our question but lets say 100.
Me: No, this would help us by how much will the Terminal increase the capacity. Ok so how many Bays would there be in the new terminal?
JC: 50
Me: And do we know on average one flight spends how much time at a Bay?
JC: 60 minutes
Me: Is that number in line with international standards or is there scope to impact that by way of terminal design or operations?
JC: No that’s about the best you can get ☺
Me: Fair is the distribution of traffic the same through out the day, or in other words is the demand pattern similar through out the day or is it varying with time? JC: Let’s assume that a bay is utilized effectively only for 12 hours in a day. Me: Ok so that means a given bay has the capacity of 2 ATMs per hour or 50 bays together would add 50 * 2 *12 or 1200 ATMs
JC: So should we add Terminal 5?
Me: Well yes from our analysis so far it does appear that adding the 5 Terminal could add upto 1200 ATMs per day and therefore one should go ahead.
JC: But what was our problem definition?
Me: (a little flustered) will the new terminal add to the capacity of the airport?
JC: yes of the entire system. So will it?
Me: (suddenly a light bulb strikes ☺, smiling) Ok I possibly get the drift of what you are trying to hint at, while the terminal has the potential to add so many ATMs, it is not necessary that the capacity of the entire system will be incremented by that number.
JC: Correct, and why that may be so? Me: Because the bottleneck in the system may be some where else.
JC: Right and so what defined a bottleneck Me: In any system the resource which has the lowest capacity and for which the implied demand is higher than its capacity constitutes a bottleneck, and also limits the throughput of the entire system.
JC: So what else could be a bottleneck in the system? Me: Runway JC: Ok and how can we find that out?
Me: We need to evaluate the utilization of the runway. How long does it typically take for a successive takeoff or landing on a given runway?
JC: How can we find that out?
Me: A mathematical way to do that would be to find the typical distance an aircraft travels while landing/takeoff and at what speed to find the time for which it uses the runway, another could be that there would be some minimum time set by the ATC/guidelines as the minimum inter flight time that would limit the number of planes that can use a runway.
JC: Right, let’s leave the mathematical way, what do you think the other number is?
Me: I don’t know for sure, but from my observation the time in India is something like 5-6 minutes between flight landings/takeoffs
JC: Ok those might be t he numbers in India, but Heathrow is a very busy airport and there the minimum time is 90 seconds.
Me: (quickly doing the numbers) 90 seconds implies 1 ATM every 1.5 minutes or a max of 40 ATMs per hour or a max of 40*24 = 960 ATMs per day per runway.
JC: Correct, so assuming there are 2 runways already what would now be the impact of adding the terminal 5 on the capacity of the system?
Me: Let’s assume that the current capacity of the terminals is X, then the current capacity of the system is min(960*2, X), and after the new terminal comes online the capacity of the system would become min(960*2, X + 1200). (I actually clearly wrote down the mathematical form) So depending on the value of X we will know how much the capacity of the system can improve by, and our decision should be driven by if that new number is enough to achieve our goal or not? For any positive value of X > 720 it seems we will only be able to go up to a max 1920 ATMs per day, without adding a new runway or decreasing inter ATM time for runway usage.
JC: Good I think we are done with the case. Do you have any quick questions for me?
Me: Sure why don’t you tell me a bit about the nature of work you have been doing and the kind of work BTO London does?
Tips: Listen carefully, especially the case question/problem framing Maintain a pleasant disposition, Do Smile Be ready to admit your mistakes and over sights Speak slowly (Especially when dealing with international interviewers) Write down stuff in your pad - write legibly Steps should be Think, Write, Read out & Discuss. Do revise the core concepts – just helps you with the right terminology in he interviews. On the interview day take each interview on by one – Never think about any that you have already given, and nor about any to come.

Round: Case Study Interview
Experience: NFK: McKinsey has done some work in innovation in the BPO and outsourced project management space..
...yes the Process 360 & Project 360 initiatives (brought in the fact that I had gone through the article. This also happens to be Noshir’s research)...
NFK: right.. they are operational excellence frameworks we have come up with to assess the best practices in the BPO and outsourced application domains.. so the question is if you were to develop a similar framework for excellence in the product development or product development outsourcing space what metrics do you think can be used to measure those?
Sure, may I just have a minute to think this over..
NFK: Ok..
(wrote down a few bullet points and then started).. We can think of different parameters/indicators at different levels – Individual/Company/Market/Users. The idea is to measure excellence in product development by not just focusing on the inputs, and the processes, but also by outputs both direct market facing and indirect outputs.We had a 1 minute discussion about each and at the end NFK seemed reasonably satisfied with the suggestions. NFK: Great, so we all know India has been known for outsourcing in the services and process space, what do you think ails the Product development? In particular I would say some companies like Adobe, Intel, TI and MS (only to a very limited extent though) have been successful at doing product development out of India, but not many others. What do these companies do differently? What do you think have been the critical success factors for them? (took a little time to ponder over things and really tried to dig into my experiences at Adobe an TI & what I thought was salient about the senior management there – therefore the lesson – do not ignore the Sr. Management talks & Company vision and strategy meetings that you used to have back in offices ☺) Well I think two overarching factors in the success of companies like Adobe and TI have been Vision of the founder & Execution, and I would want to break down Execution further into 1) Hiring & focus on employee growth, 2) Process & Discipline, 3) Sr. Management Commitment & push back, 4) Clear & continuous communication with the International parent. It might be a coincidence but in the case of both Adobe and TI, their India offices have been led by very strong and committed senior leadership teams who have grown from within the parent companies’ home operations. Therefore, one they knew what were the parent’s best practices, and two they had the ambition to set up something in India and make it succeed. Then once they had the go ahead they focused single mindedly on the execution.... NFK: What do you think are the key strategic challenges for a company like Infosys going forward? (again after a minute of pause and jotting down stuff) I think the three key challenges would be 1) How to remain competitive now that they are in the 4B+ league and starting to compete with the big league of IBMs, Accentures, EDS etc, not just in outsourcing but end to end IT management 2) How to manage such a huge work force and manage their skills 3) How to remain relevant in the face of changing business models specially the move to hosted & cloud computing and software as a service models. NFK: Let’s talk more about the 3rd one! (He immediately latched on to the cloud computing thing.. so this is an example of a hot word for a particular interviewer) We then had a lively discussion on what cloud computing and Software as a service and software on demand is etc., and what impact can it have for IT companies and their business models. NFK: Good. Any questions that you may have for us I asked on what the role definition of BTO was and how was it different from the high-tech practice of McKinsey?
Tips: If possible do read a bit about the interviewer’s background. You wouldn’t get to know your exact interviewers till shortly before the interview so you obviously can’t read about all, but try to read up about the senior people as well as people who will be from similar backgrounds as yourself. Excellent way to do that is to get on to company sites and browse for interview panelists profiles. In the case of McKinsey, try to get to McKinsey Quarterly, and then search for the interviewer and articles written by the person Be prepared to get the broad discussion cases even in the first round. Have a perspective on the industry of your choice and or background – again a good way to do that is to browse articles and industry reports. If you are able to go through even one consulting firms site reasonably you should be in good shape. Try to change the plane of your answers depending on the interviewers interests – when to give thr 50,000 Ft view and when to give the 100 ft view. In hind sight I think the corporate strategy course had a lot of articles about outsourcing and different models of comp advantage for multinational organizations and how to leverage offices in different geographies. Though I myself didn’t recall much of that article but then it just shows you never know which reading might come in handy where ☺Have questions that you want to ask ready

Round: Case Study Interview
Experience: LHR airport is building Terminal 5. Why? Identified the purpose of terminals, and its physical layout. Defined capacity as throughput of baggage (big mistake: capacity here was supposed to be that of airport with runways being the bottleneck!!). Compared capacity of T-5 with that of other terminals. Basically, T-5 is being built to accommodate the A380. I knew this from my GK but didn’t exactly shine through in the interview.
Identified it as an operations issue. After that everything went downhill. About halfway through the interview, I realized that I was dinged anyhow (I’d have rejected me had I been the interviewer), so there was less pressure and I had a relaxed time with the case after that.
Tips: Don’t neglect operations based cases. These were the least favorite ones of mine during prep. Even if interviewer is hostile, keep a cool head and think logically, don’t let the pressure get to you

Round: Case Study Interview
Experience: We started the interview with a 3-4 minute chat about how painful it can be in the morning to travel and start working right away (He had just arrived).

He then quizzed me about leadership instances at work and in academic career; then I took him into what he believed leadership was. We had a long chat about why leadership was important in consulting. We also spoke about how I was to translate a very explicit form of leadership displayed at work (I was leading operations in a factory) to an implicit environment (like consulting). We talked about what leadership skills are transferable and ones which are not.

The case was about a global heavy vehicle manufacturer. The firm was planning to enter India; my job was to devise a strategy for it. A simple case to begin with I thought, but I knew very well that the challenges are higher in a simple case.
I started off with a simple framework (nothing great, decided the marketing mix and the way to enter – organic was the better route). I also identified the capabilities of the manufacturer that could be transferred to this setting. This went on for about 10 minutes. Here it was important to structure the problem well, following a MECE structure. I also shared some experience of a project with him that we had done in Competitive strategy project that we had done on cars and shared some uniqueness of thenIndian market with him. I am not covering this in detail as it was pretty standard and I just had to do the basics right. Then he told me to size the truck market in India. I told him that I will follow the stock method of analysis, by which I will estimate the number of trucks currently in operation throughout India. Since I was doing a demand side analysis, I divided the trucks into
variable loads (where capacity utilization is less than equal to 100%) or fixed loads (construction equipment carriers, petrol loads, car containers, etc.). He said that they normally don’t do it this way but he wanted me to proceed as he found it interesting.

Then, he told me that he wanted me to do it for the car carriers for paucity of time. I went ahead and assumed a certain number of carriers that are bought every year (the number wasn’t important, I assumed 1000 for ease of analysis). I understood the supply chain from him and he explained the dealer system to me. Then, I told him that I will assume steady state, as in the number of cars sold are the number of cars manufactured and distributed. I then divided it as per the number of manufacturers, number and location of manufacturing locations, distance, speed distribution, capacity of trucks, capacity utilization, number of hours driven in a day, maintenance days and the average number of days that a truck is driven in a year to arrive at the number of trips made and hence, the number of trucks that were plying. It was important to note that the trucks generally came back completely empty. I also told him that the transporters will like to keep some number of trucks on a standby. He asked me to estimate that as well. I gave him a framework to analyze that. I gave him a framework depending on locations, routes, failure time and MTBFs. He was ok with that. The case was extremely quantitative and was very intensive numerically. I also did a sensitivity analysis on one of the
parameters showing him that the whole estimate was sensitive to a few parameters.
Then, I told him that if I link both the cases together, then it gives me an interesting sight into what value proposition the truck
manufacturer can give to the Indian transporters. I told him that let’s look at each of the variables that I had estimated earlier and
see whether we can reduce them. Then, I said that we can try to increase the mileage and increase the size of the truck as well. Then, I told him that both the things might be inversely related. It can also be done that the truck speed can be increased on the back journey. Maintenance days can be decreased. He asked me for a few creative recommendations, which I gave – I don’t really remember them now but the method was as stated above.

Then, he asked me for a feedback about the case and discussion overall. I told him about how different the case would have been
had the case between about variable loads. He was ok with it.

He then told me to ask him a question. I asked him about the project specifically and to what detail McKinsey went. I also asked him how McKinsey keeps a tab on how clients implement suggestions. The overall case lasted about 25 minutes. I then linked it with one of the questions asked in the personal interview. I told him that it is a challenge that line managers like us will face in a
consulting environment, wherein we do not necessarily get to implement. Then, I shared a few jokes that I had played with consultants (mostly technical) and how it might be my turn to be on the receiving end now.
Tips: I think the skill that was being tested here was how comfortable I was with the interviewer in the beginning. It was important to
engage him in a fruitful conversation that is argumentative but not confrontational. I think basic presence and communication skills were being tested here. Overall, the whole experience lasted about 10 minutes, and when he was convinced that I was comfortable enough, we went into the case.
It is important to be your natural self in the interview. Comfort with numbers is absolutely crucial. It is also important that when using creativity, structure should not be lost. Never shoot ideas of the hat, always be structured. It is important to see and address the body language of the interviewer. The basic thing that works is that one should focus on bringing out one’s strengths in the interview. My strengths lay in creativity, structuring and quick calculations (which I specifically tried to bring out in the interview). Your strengths (preparation will yield that) could be very different and you should try to bring them out. It is very important to remain cool after the interview since one might get a feeling that he’s not done well but the results could be just the other way round!

Round: Case Study Interview
Experience: We started the interview with a conversation about my career at IIT and my times in Cuttack (Orissa), my hometown. He was hooked onto my JEE rank and asked me why the number was unique. I don’t think he wanted a particularly great answer but he wanted to check my ability to think on my feet. He asked to give him 5 different uniquenesses.

He also asked me why Cuttack wasn’t doing as well as a Bhubaneswar. To this I replied taking geographic, political, cultural and economic reasons into account. We then discussed about my Summer Project with Reckitt Benckiser (this was an automation project with a FMCG major). He asked me to explain the labor implications of implementing automation. He then went ahead to ask me my experiences in dealing with unionized labor at ITC. He was also interested in one of the papers that I had written about
BOP and presented at XLRI. This was about how to bring your best people to the BOP. He asked me to explain the paper and then told me to explain how useful it can be to the corporate world. My observation had told me that he was very practical and won’t like flowery answers that this is the idea of the millennium! I gave him all the strengths and weaknesses of the idea (and real ground level ones) in implementation.

After that he asked me why I was looking forward to a consulting career. I told him that it links well to my long term goal, which is
leading a NGO. I told him that this is one of the reasons that McKinsey stands out for me as a firm, with all the public policy and
pro-bono work. We discussed a bit about India’s policy change from the ‘50s to the ‘70s. I gave him some funda about what I had
seen in the Commanding Heights video, though he was doing most of the talking.

He was visibly happy with the fact that I said public policy (Later I realized that he specializes in public policy at McK) and told me
that he will give me a case on it. The whole experience lasted 15 minutes.

He started off the case asking me what I knew about the Bharat Nirman Project. I told him that my knowledge is limited to what I have read in the papers over the past few weeks and I do not know in detail about it. He told me that this case will enhance my
learning about the challenges facing somebody working in public policy.

The case was about rural electrification. He said the objective of the central government has now shifted to putting an electric bulb in every Indian home by Feb, 2008. He asked me how the Government should go about it.

I started off telling him that the idea looked unrealistic to me. Assuming that 1 billion is the Indian population and 65% lived in
villages, 650 million is the current rural population. Assuming that there are 5 members per rural household, there are 130 million
households. Then assuming that 30% of rural India is electrified, 91 million households remain. We just have two years, which is
approximately 700 days. Even if we work throughout, 1.3 lakh households have to be electrified every day. This is by no means
easy. Add to this fact that there is huge geographic dispersion and the current state of the SEBs, the plan looks nonviable. I told him that I found it impractical. To this he replied saying that most public policy projects are such. They lack thinking about the design phase itself. He asked me to go ahead with the problem assuming it is doable.

I approached the problem saying that I would see the project from three standpoints – economic, organizational and operational. On the operational point, I would divide the project into generation and T&D phases. On the economic standpoint, I would look at the ways and means to fund this project. On the organizational front, I would like to see who would own this project. Here, he told me that the question should not be treated like any other consulting case and he is looking for completely creative solutions.

I asked him whether I should go ahead with the analysis the way I had structured or he wanted me to do something different. He
replied that he is looking for specifically the Generation area. I told him that when it comes to generation, there are four issues
that need to be looked at – Performance of conventional energy generation units, New conventional energy units, isolated units and non-conventional sources of energy. He said that I should discuss the non-conventional energy sources first.

I told him that I was aware of solar, wind and bagas (sugarcane by product). He asked me to describe the economics of Solar. I showed it to him that at the current rate, it’s unprofitable. Then, we went to Wind energy. I told him that the issues to look for
here are technology, fixed costs and practical viability (availability of areas) where they can be installed. We discussed each one of
them in greater detail from then on.

I told him that when it comes to buying technology, it would be very costly and technology transfer has to be on a mutual basis.
Then, we went it to the details of the windmill technology and its advantages in the Indian context. He was doing most of the talking here.

He asked me to do a commercial evaluation of all these technologies. I did the same considering three parameters – speed (because the industry has an external effect), cost and future viability (to incorporate learning curve effects). After shedding
some light on each one of them, he asked me to move on to the funding aspect in generation.

I told him that the money here can be drawn from four areas – government, Indian private, Foreign players and debtors. I told him how each one of them was different (most of the logic was thought on the spot). We then discussed about the amount of privatization that should be allowed. I was of the opinion that wherever private participation is allowed, it should be in both R&D and generation. Having only one of them was not of any use. He didn’t agree to it and he was of the opinion that we weren’t ready yet. We closed the interview on an argumentative note.

He asked me to ask a question at the end. I asked him what kind of persuasive powers consultants enjoy when it comes to public policy projects. He smiled and gave me a lot of insight into public policy consulting. He appreciated the fact at the end of the interview that I could make people talk. The whole experience lasted close to 20 mins.
Tips: Keep your cool. Show a good understanding of the things happening around you (may not be knowledge, but an opinion usually helps). Do not try to throw facts when they amount to nothing!

Round: Case Study Interview
Experience: He asked me about the problems that dealing with a union entails. There were a few more specific questions about my resume, in
which I had to describe the work I did. I spoke for some time – maybe 2 minutes.

Then he asked me the kind of preparation that our batch had done for consulting. I gave him some feedback about how the interview workshop process done by McKinsey could have been better and how different it was from other colleges (stressing on poor institutional memory and ways to deal with it). He asked me what my last case was about. When I told him that it was about public policy and I had like it. He said that he also wanted me to do a case in that. The whole conversation lasted close to a little over 10 minutes.

An extremely short case. It lasted less than 10 minutes. He asked me what a government could do to improve the banking
policy of a third-world country. To begin with, I told him that there is no generic answer and the policy has to be case specific. I also told him that I got a feeling that he was speaking from personal experience.

He said that I was right and asked me to take the case of Bahrain. He asked me what I knew about Bahrain and its banking industry. I told him that I knew it was a Muslim country and was staunch in protecting Muslim values (I used to collect stamps; I knew that they did not have a word of English – I told him that).

Then he gave me a good overview about Bahrain (lot of tangential stuff) and told me that the Finance minister was worried that the industry might lose it. He told me it was majorly into fostering corporate banks.

To begin with I told him that it was a case of B2B marketing and banks would stay if they get a good value proposition in Bahrain.
But then, if they get a better value proposition elsewhere, they’ll shift. He said I was right and asked me to think ahead. I asked him who these banks were. He told me that they were the Middle East bases of MNC banks. I asked him why the banks were there in the first case. He told me that it was centrally located and had liberal laws. I analyzed the geography and told him that what struck me was the fact it was close to Dubai. I asked him why not Dubai?

He told me that there was an announcement by the Dubai officials that they would make their policies freer than Bahrain and would make it a free trading zone.

I inferred from this saying that this might be a symptom of the real issue but wasn’t the actual problem. To this, he agreed. I told him that first of all I need to analyze the Dubai threat more closely. I told him first that we need to establish whether Dubai’s threat is credible or not (look at their history and look at the economic impact). He asked me to assume that they can do it. Then, I told him to look at the value proposition (including the switching cost to Dubai – local knowledge, skill base) that Bahrain provides and compare to the value proposition that Dubai gives. I told him that it is important to keep a futuristic view in mind. Then, I told him that what strikes me about the case is the fact that in this industry, it is very important to build your local clientele and not rely on foreigners. He said fine.

Then, I quizzed him about how developed was Bahrain’s retail and corporate banking was. I told him that it would relate very closely to the economic development was in Bahrain.

I told him that I felt that the real issue with Bahrain was the fact that the industry relied too much on MNCs without first satisfying local demand. I told him that I would like to create a policy keeping this in mind.

He asked me to stop the interview then and there.
Tips: Thinking on your feet is extremely important at the beginning of the case. First think commonsensical and then get on to the regular consulting case analysis. One way of dealing with a person you know is to use your previous experience with him (in any which way).

Round: Other Interview
Experience: I was told at the beginning that I won’t have a case. He asked me to ask a few questions that I felt were relevant.

I asked him how McKinsey makes the environment conducive for knowledge sharing. He gave me a few inputs.

I told him what I had read about McKinsey’s knowledge management in a HBS case. He heard it attentively. He then gave me an idea about the state of affairs now and particularly in India. I asked him about how sharing gets linked to performance initiatives. I also asked him how other firms (esp. consulting) do it. He then asked me to narrate a few instances about ISB. I told him that any education program is incomplete without pranks. I told him a few pranks that I had played on a few friends in ISB (and vice versa).
Tips: Be your natural self and try to gauge the interviewer’s body language when telling a story.

General Tips: 1. One of the key facets is to make the case completely seamless, wherein you have to link both the PI and cases and both the cases together.
2. Structuring is very important.
3. The other thing is to make the interviewer comfortable.
4. Do not speak a little too much.
5. With seniors, I think it is very important to listen.
6. It is also important to observe as you go along the interview process that every interviewer is looking for a particular skill or dimension in your personality.
7. It is also important that whenever you give a radical thought, you should back it up by sound strong logic.
8. Control the interview.
9. A bit of formal attitude would help.

Round: Case Study Interview
Experience: The interview started with a 'tell me about yourself' for which i had prepared a 1 minute intro highlighting specific aspects about myself that I wanted to bring to his notice . Then he asked me about what i did in CRISIL (my prior workplace) . I explained that I was engaged in assigning Credit Ratings to Corporates under Basel II Regulations.
How would you go about Rating a Company, lets say Bharti Airtel.
Because it was Bharti Airtel I had to give an answer tailored to what the approach would be for a Telecom company would be. While answering I was conscious of 2 things – One, that I have a clear structure to my answers and Two, tried to keep it as simple and jargon free as possible.
(An Offshoot from something I had mentioned in the earlier answer) What are the ratios that you would look at?Here I mentioned the financial ratios that I would look at stating specifically why I would look at each ratio. He probed me on a few ratios here and there. The intention appeared to be more to check my articulation of a financial concept.
Eg: What is a Current Ratio?
I explained the formula. However I did not stop there. I went on to explain that it was used to assess the liquidity position of the company.
Then I went on to explain to the logic behind the usage of the ratio – Simply put, it tells us if there is likely to be sufficient inflows of funds over the next one year to meet the maturing payment obligations. So a current ratio of less than one means the company has more to pay than what is coming in, a liquidity problem. (Based on the approving nods that I was getting, I felt he liked those portions of my answer where I endeavored to de-jargonize or simplify complex concepts)
So Tell me, how would you increase the revenues of Bharti Airtel.
That was my case, it had begun. However, at that point I thought it was just an extension of my previous discussion and I started rambling.
Analysis:
Preliminary questions - We all know Bharti Airtel and the services it offered quite well – So there was no need to ask preliminary questions. Also, since I wasn't aware that I was doing a case I did not have the opportunity to ask preliminary questions.
Structure: The Structure that I used was fairly simple – Increase in Revenues can in Existing markets or through expansion in new markets.
I explored the existing markets first. Here increase in revenues could occur through increased market penetration, increased usage of basic services among current users or increased usage of Value added services among existing customers. He asked me a couple of questions on how these things can be done and I gave him some off the cuff answers.
For the New markets, I suggested that the company could look at inorganic expansion through acquisitions or through establishment of Greenfield operations in new markets with high market potential.
The entire case was more like an informal chat. There were a few follow up questions on some of the options I had generated. The case did not last very long – about 10 minutes at the max.


Tips: Know your Resume well. At no point in the interview should you ramble on. All answers must be natural (ie, must not appear rehearsed), brief, structured and to the point.

Retaining composure through the interview is critical. Mistakes may happen during the interview, but it is important to pick you up and keep at it. People rarely have perfect interviews where everything has gone right and interviewers don‟t expect it either.

Round: Case Study Interview
Experience: Case: I am the manufacturer of Tata Nano. While setting up the plant I expected to have sales of around 5 lac Nanos per annum, but now the number is way below that. Can you help me find out why.
Analysis: Preliminary questions – Since it was Tata Nano, lot of the background questions were not required. I clarified whether the problem was a lack of bookings that they received. He agreed.
Structure: The Structure that I used was not the best but it did get me to the problem. I started off by saying the lack of bookings could be on account of 3 reasons – One, a lack of awareness of the product among the target customers (Marketing problem), Two, Being aware of the product but not being able to place a booking (Distribution problem) or a Three, being aware of the product yet not interested in the product(i called this the product problem). He asked me to ignore the first 2 (he did not seem highly impressed) and explore the 3 rd the product problem.
Here I again broke it up in to 2 further branches – Problems that the Car has by itself (Internal factors) and problems in the external environment mainly competition, etc. I deep delved in to the Internal factors.
Of the internal problems I mentioned, he agreed that the negative publicity from the steering wheel catching fire was an issue and comfort factor was another issue. As and when he acknowledged a problem, I made a separate note of it. Eventually when he asked me to explore the external factors, I used these points to do a quick summary of the key takeaways up to that point.
In the external problem, I divided it into competition from other cars and two wheeler. I asked a few questions here trying to pick up a clue or 2 of how to proceed from there but he just refused to shell out any information. At this point he also took out his Blackberry and acted uncooperative. I went on to analyze for myself that given that the price of the next cheapest car was over a lakh higher than this car the issue lay more with the 2 wheeler. I went on to list factors why people would prefer 2 wheeler to a Tata Nano. Of the factors I listed, he acknowledged that the high running costs and availability of easy financing options seemed like the distinguishing factors. He said I seemed to have arrived at the problem.
He now asked me to tell me how he could provide
financing options for the Nano. This I felt was like a
guess estimate problem. I said I would work backward
to solve the problem. This is how I solved it – I said the average Nano target customer would earn Rs 10000 per month (he had given me that number in an earlier discussion, he liked the fact that I had noted it down and was using it again) I said, given the average savings rate of the country is at 35%-40% (this is from the RBI website I think). That meant a saving of about Rs 4,000 per month. No one would be comfortable giving up their

Round: Case Study Interview
Experience: PI Questions came after the case. It started with interviewer asking about my prior work experience. All subsequent questions emanated from the first question which was: “Of all your achievements, which one do you think is the most important to you”. This was a classic case of being able to draw the interviewer to where you want to go. I talked about a very tough implementation project that I did at ITC Factory in Munger, Bihar. I said for me an achievement is about 2 things: (1) The Context in which I
achieved it (2) What it meant to me at that stage. In the context part, I talked about managing an un-skilled workforce.
Then he asked me how do you manage such a work force? I said by established an internal connect with them. He asked how do you do that? Went into a couple of instances which made me establish such connections. Although he had asked me to talk about just 1 instance, but seeing that he was impressed, I requested him if I could talk of another different type of incident which is also very close to my heart. He allowed. I talked about selling a extravagant project to the company chairman. It was
about high-end world class patented Audio-Visual systems. interviewer too seemed to have some knowledge about those equipments and thus we had an interesting conversation. The idea was, I could not only show my Project Implementation Abilities
but also talk about Planning and Inter-personal skills.

The case was about a canned juice manufacturing company. Recently they have diversified into different types/more variety of juices. Their profitability has gone down in comparison to their competitors. Need to analyze, identify root causes and advice solutions to the client. I asked a few ‘Start-Up’ question These are standard questions which you would ask for most of the cases. Some of them were: How big is the client? Has been in the business for how long and how and when has their business strategy changed. Who are the major competitors? What are the various revenue streams (different type of juices et al)? He gave
me some info but asked to assume one standard fruit juice for the analysis. Now I approached in the classical Profitability Case. Profit = Revenue – Cost. Problem can be in either of the two factors i.e. Revenue or Cost. I asked him if he wanted to delve into Revenue or Cost first. He advised to go into the cost aspect (we never visited the revenue aspect). Then he asked me about what are the various cost heads in such a business. This was the key!!! Process Value Chain rules I drew the entire value
chain from Agri-sourcing of fruits to In-Bound Logistics to Warehousing to Processing/Manufacturing to Out-Bound Logistics to Retailer to Customer. Started from the Left Side i.e. Sourcing. He asked me what could be reasons for lower profits. This was more of a brainstorming session. Coming from ITC (of e-choupal fame) background, I could talk the possibility of competitors being able to backward integrate and establish a symbiotic relationship with the farmers which allows them to remove the middle-men and thus get cheaper and good quality fruits, whereas our client has not done that. Then came to In-Bound logistics. I
said that juicy fruits being mostly hygroscopic are prone to damage in transit. Talked about the quality of infrastructure en-route to their plants and quality of logistics partner. Then came the crux: Processing/Manufacturing. At first it was qualitative.
I said the client might have a very high Cost/Unit because of excess/high quality infrastructure. Somehow this turned out to be the case. I realized there has been loads of ‘strategy’ based talking and there bound to be some nos. I asked him and he gave me whole lot of nos. about their manufacturing costs as well as the manufacturing costs of competitors. There was Maths involved here as he gave costs and throughputs of different plants of client as well as competition. Had to find out the average cost per unit of juice manufactured by client vs competition. Of course client’s cost of manufacturing was way higher. Talked about some ways as to how can this be brought down. Talked about economies of scale as some of the assets were under-utilized. This would involve launching other related products as well or expanding markets. There were a few more points discussed but this was merely a closure.
Asked him a couple of questions on his area of expertise and how markets were shaping this year.

I believe that your work-experience (which is a huge factor in your being short-listed) must be reflected in the way you approach cases. Sometime we lose sight of that in following standard structures/frameworks etc. At each stage, I could use my FMCG and Manufacturing experience to come up possible reasons. So, your experiences must show in case solving as well and I believe I did that well. One very interesting thing, right at the start which I think worked well for me. When I entered the room, I generally talked about the view being great from the window. Nal generally asked whose room was it. I had not noticed the name-plate while entering which anyways was covered with a McKinsey signage. Looking at the books and brochures in the room, I
made a guess giving the reason of the guess. It was Bang On!!!

Tips: Do not lose sight of Who you are and What have you achieved till date.This should reflect in your interview. Also, be ready to delve into nos. Interviewer also wants to test your analytic ability with nos. as they back/justify your claims, ideas and suggestions. So ask him if he has nos. when he says “Cost is High” or “Profits are Low” etc.


Round: Case Study Interview
Experience: Just imagine. It does not get bigger than him. The senior most guy in the panel who is rumored to take the final call on each and every candidate. I was to interview with him in my Round-1. Thought this was the do or die situation. Questions started coming right from my CV. We talked about taking up very good projects additional to normal course curriculum, participation in sports, organizing ILS and some other personal focus areas for the year. Then he asked which one of the 3 academic experiences: School,
Undergrad, ISB was most enriching. I split it into 2: Academic and Over- all. Academic was School and Over-all was Undergrad for me. He asked me the reason. Came from the CV plus how it was important for personality development and so on… Then he asked about my work-experience. Talked about CAPEX for a while. What did I do as Capex Manager etc.

Started off with the standard warm-up questions but somehow warm-up questions and interviewer don’t go too well. I asked him about the background of the company/competition/industry. For each question I was quizzed on why did I think that question was
relevant and how will it help me achieve the final objective i.e. valuation. Some useful information which I could generate was that the ‘patent’ was for cotton farming and would increase the yield of cotton growth. Realizing that it was a valuation case, I proposed following the a combination of 3 approaches -(1) Value Based Costing (2) Competition Based Costing (3) Cost-Up; to come up with a band of prices and then zero-in on the final price based on other factors. He agreed. Started with Value i.e. Willingness to Pay on the part of the customer. The customers would of course be cotton formers. Then he asked what is the value of the patent to them? I told him about it increasing the yield and asked if he could provide some nos. on the same. He said it increases the yield per sq. ft by a factor of 50%. Believing that it would again be a complicated nos. case, I took some time and came up with a complicated structure to calculate the monetary value of this increase in yield. It involved numerous factors such as average land-holing, no. of cotton farmers, current yield, cotton prices in the market etc. etc. But rest-assured interviewer cases would rarely involve complicated calculations. He said he was looking for something very simple and asked me to think about it.

Now was the moment of surprise. While I was thinking, he asked me to pause. He said “Oh you have worked in Capex right? How would you reduce Capex Cost in a Power Plant?” I was really surprised. I started off by giving him a ‘structure’ (yeah right!!!) which we need to put in place to identify the scope of reduction in Capex. I came up with various stages involved in setting up and commissioning a power plant which would be:
Engineering Design > Construction of Infrastructure > Procurement of equipments > Electricity Generation > Electricity Distribution & Transmission
Told him we need to look into Capex requirement at each of stage and started off with Engineering Design. Just I as started, he asked me to go back to the Patent Case (strange!!!!)

He wanted a simplified model to calculate the value. After some discussion, we have me the annual turnover of cotton in India and the average price per ton. From this I calculate the value of the higher yield that all Indian farmers could get.

He asked apart from increasing revenue, how else the patent could benefit the farmers. Now with revenue there has to be cost!!! I said the new technology could lead to reduction in costs. Was asked to brainstorm on the costs involved. I told land, water for irrigation etc. Yes the patent reduced irrigation requirements. So I talked about reducing water consumption, associated energy costs as well as the psychological costs and risks associated with reliance on monsoons which could now be mitigated. He asked what else? Very happily I told him that now lesser seeds may be required. He said “The patent is a variety of seeds only”. I realized I had forgotten to ask him what does the ‘patent’ entail….in one of the professor’s language, “is it a bird or a plane”. Should have asked it upfront.

Anyways recovered. Had already found out of the increase in revenue (was asked to neglect decrease in costs) . Told him this would be the maximum willingness to pay and thus the upper end of the price band. He agreed. Asked him the cost of Research and Development. He asked why? Told him this would be the lower end of the price band unless the focus was not profitability but social upliftment. He said the focus was completely profitability and gave me a Net Present Value (assume N). Could not understand it immediately but realized that it is Revenue net the costs. Thus, the price band for the patent (in NPV terms) would be between Rs. 0 to N. He agreed and asked me to zero down on a value. Told him we need to look at similar launches in the past to capture some trend (and therefore arrive at a value in the middle) but he cut me short and said that no need to look at past records and
you would price it at less than N as we need to incentive the farmers to overcome their switching costs by passing on some benefit to them. Now this is what I eventually wanted to say but could not.

Firstly it seemed that Nothing went right. I wasn’t confident interviewing with him. Missed basic pointers and took time to identify the ‘simple’ model he was looking for. And of course couldn’t conclude well. But, later I was told, what went right was the CAPEX piece He wanted to test how good I was with my basics while I was caught up doing something else. Can’t expect this from anyone but him. The framework was bang on!!!

Got a bit psyched. Could not structure the Patent Case well and it was more of bouncing off ideas. But was later told this is what happens with everyone when they interview with him



Tips: Can’t emphasize more the need to be thorough with your work-ex and reflect your experience in the case. And if can, be confident no matter whosoever is interviewing you. Please remember, you know stuff much better than the interviewer. You have slogged your back while working. Who else would know about it better?


Round: Case Study Interview
Experience: I was told that he was very keen to meet me because of my Operations background and was especially interested in my CAPEX experience. I was told that he wanted to know more about what I had done during that stint. So I went in with the frame of mind that I have to maximize on that aspect of my profile. As expected, he asked me thread bare on what all I did in that stint. He did try to intimidate me by passing a few sarcastic remarks but I seemed to enjoy it and gave him appropriate responses. Then he asked a very interesting “What do I expect to hear if I were to go out and ask people randomly what they thought about you?” Now
McKinsey allows you to be innovative, frank and candid in such questions. But these need to be backed by some logic. Told him that different people are entitle to have different opinions about a person and how my different types of interactions i.e. in class, in events, in sports would result in varied responses. Also, talked about the situational aspect of it being 1st Day of placements and how that could influence the responses. Then came up with a few candid ones. You can call me to
find those out

Was told this is a short case and we need to wrap up the case fast. Without asking too many ‘Start-Up’ questions, came to the 3 dimensional approach of (1) Value to Customer (Willingness to Pay) (2) Competition (3) Cost-up. Started with Value. Was asked to brainstorm on how could this service be valuable to the customers? Talked about the qualitative aspects of Mumbai traffic having various tangible and in-tangible costs. Tangible benefits could be saving of time, fuel and fare. Intangible benefits could be alleviation of psychological costs like being stuck in traffic and getting to spend less valuable time at work and office. But he said that fare is something we need to find outThen moved to the 2nd aspect of competition. Asked him what were the other modes of transport available to the public? He said two alternatives existed- Road (Taxi) and Rail (Train). Asked him information on Time and Cost. Don’t remember the exact nos. so will use indicative figures. By Taxi you took 45 minutes and incurred costs (all inclusive- tangible + intangible) of Rs. 250. By train you took 30 minutes and incurred costs of Rs. 50. Now asked him the time supposed to be taken by Hovercraft and how many of them were there. He said that a hovercraft would take 20 minutes to cover the distance. The company was planning to start off with just 1 hovercraft. Asked him it’s capacity and he gave a figure of 100 people. In a flash of rushing ideas, I just said that then there would be a capacity constraint or atleast the hovercraft would always be full as the no. of travelers would far exceed 100 in a busy place like Mumbai. Although at that stage I didn’t know how this was important in the context of the case but he liked it Ok, coming back. Hovercraft saves 25 minutes over Taxi and 10 minutes
over Train. So though would try and valuate in monetary terms this saving of 25 minutes and 10 minutes. But point to note is that cost of Train is much lower than cost of Taxi. So, value based approach if applied on both the modes would result in two different nos. poles apart. He quizzed me how to proceed and after some discussion, I concluded that it made no business sense for the Hovercraft company to compete with the Train and thus focus on competing with the Taxi only. Plus, with only 100 seats, there would be no issue of in-sufficient traffic. Now this is where the earlier remark on capacity made sense At this stage he asked me to synthesize by giving an elevator pitch to the client CEO, asked me to fit it in 1 minute and started looking at his watch saying I was being evaluated for brevity. To wrap up, knowing that he Head the Ops practice, I asked him a question on benchmarking in operations and whether Indian firms are at a stage where they can be set as international benchmarks. Surprisingly,
he asked me why I wanted to know about it. Now this was strange as I had never ever heard of an interviewer asking the interviewee a counter question on the closing question. I told him how we had to benchmark many of our expansion/ up gradation projects with Japanese firms and wanted a view from someone who has been exposed to such facilities across the world. He was satisfied and then answered the question.

Discussion on Work-ex. Taking the sarcastic remarks in the right way and not getting intimidated. Again reflecting the learning from the work- experience in the case.

The synthesis could have been better. His staring at the watch for an accurate 1 min pitch intimidated me a bit. My bad. Otherwise nothing much was wrong here.


Tips: Again, work-ex thoroughness is imperative. Think through carefully the closing questions that the interviewer offers to answer at the end of the interview. The questions need to make sense in the backdrop of your profile, experiences and those of the interviewer.


Round: Case Study Interview
Experience: PI came after a couple of cases. This PI for this interview too was Work- Ex centric. Noshir asked me about the two most important leadership instances in me work life. Again my idea here was to use these 2 instances to reflect upon 2 different sides of my profile. First example was of course on leading one very tough project in a logistically challenging location. The other was captaining my ex-company’s cricket team which comprised of my bosses and super-bosses, and the leadership tools that you need to put into use in such situations.

This 11th interview of the day and for sure the final/most critical interview for McKinsey. When I was given the first case on Tata Nano, he could figure out looking at the time of the day as well as the previous few interviews that all he wanted was a structured brain-storming output on strategic cost management. So, I did not spend any time on asking clarifications/start-up questions and got down to business. As there wasn’t any readymade framework/structure for this, I imagined myself a part of the Nano team and thought through the sequence in which the material design and procurement process would unfold (of course, again, my experiences at work came in very handy). After a minute of thought, I started off by saying that this was a huge cut- down on costs (by almost 75%) thus process improvements won’t suffice and that it called for radical changes in the design and sourcing
processes. I then recommended that we should first identify the various steps that are involved in the material procurement process and see how we can cut costs in each one of them. The sequence I gave was as
follows: Technical Specifications of the car and individual parts and sub- assemblies > Preparing the Bill of Materials (BOM) > Identification and Selection of Vendors > Negotiations > Logistics- Freight, Duties, Insurance, Taxes etc.
I asked interviewer for his approval which he promptly gave. Then I brain- stormed various ways of cutting costs as each step. Car & Parts Specifications: Car to adhere to the bare minimum specifications that are needed to be adhered to by Indian Rules n Regulations (E.g. no need to Euro N+1 of Euro N compliance required in India) but without compromise on the safety of the passenger which is very important. Technical Specifications of the parts and sub-assemblies to the at Minimum Technical Standard (MTS) i.e. the specs need to be just right to meet the requirements. Bill of Materials (BOM): Talked about how big companies being risk averse always order and add extra quantity of material in everything. E.g. if 90 kgs steel is required, they would order 100 kgs and end up putting 95 kgs. So optimal safety margins need to defined and be adhered to.

Identification and Selection of Vendors: Said for experience that big companies chose their trusted and loyal vendors, and are inclined to have single vendors/point of contact for a plethora of related/unrelated materials. This way, the vendors make unnecessary money. Thus, to manufacture the lowest car in the world, we need to rationally evaluate vendors outside our ‘Zone of Comfort’ and their scope of supplies. Talked for Chinese manufacturers that give both cost and quality advantage. Gave examples of some proposals of Chinese manufacturers that I had evaluated at work.

Negotiations: Then, negotiate hard. Tata can use their buyer power (multiple businesses and product lines) to fleece suppliers but showing them possible opportunities in near future.

Logistics- Freight, Clearance etc.: This was a pure brainstorming session with ideas like bulk shipments through sea (no part shipments, air freights etc.). Centralized insurance and clearance agents. Managing road taxes etc.

Finally, something which is typically talked of in manufacturing: INNOVATION. Although setting Indica as an anchor and working backwards is a possible way, big companies like Tata Motors which have presence in the foreign markets (talked of JLR) and access to the modern technology, must mobilize their R&D department to come up with revolutionary car design. Some cutting-edge innovation like a new cost effective fuel injection system etc.

Whoa…I spoke for 20 minutes continuously non-stop. Did not find the need to. Interviewer was constantly smiling and acknowledging.

Then straight away came the second case on IT. Now that’s his area of expertise and he wanted to check if I could talk about an industry I had no prior exposure to. I came to know later that this case was in some past year’s case-book and he had written a paper on that. Anyways, I had missed both

Again I gave the initial questions a pass and asked for a minute to think. Exhausted after so many cases, I was not able to recollect any jazzy structure and thus stuck to the basics. I proposed looking at 2 types of factors/aspects which need to looked at by the IT giants of the country:

(1) Internal Factors (2) External Factors
Told him that I am a firm believer that any individual/organization should first have an internal introspection and then start looking at the world outside. Thus would recommend starting off with the Internal Factors. He smiled and said go-ahead. Internal factors meant how the company needs to improve and uplift it-self internally. Said the biggest assets for IT firms were its people and it boiled down to (a) Productivity (b) Innovation. (a) Productivity: Here, I used Productivity = f(Efficiency, Effectiveness) .
Explained the difference between the two and gave some ideas on how IT industries could do that. We could see Microsoft from one of the windows so pointed out and shared some experiences I had while I was visiting an old friend there. (b) Innovation: This is always a safe point to say. No one will challenge Innovation as an improvement measure . Talked a bit about Google
and how it fostered a culture of innovation. This again translated to sound people practices. (2) External Factors: Here I used the 3 Us framework in disguise- Users, Uses, Usage. Users: Talked about IT firms expanding their user base in India and un-explored markets abroad. Once, once you get an organization on-board, need to penetrate to all departments. Uses: Used some SAIT funds to discuss codability and measurability. How certain key process where still handled by companies internally (gave example
from work) as they were highly strategic in nature. Here, IT firms could built enhance their credibility and build stronger partnerships with the clients. Usage: Discussed growth through service provisions like AMCs etc. And then of course, Mergers and Acquisition abroad. Talk of more and more Indian firm’s expanding outside India through this medium and how biggies like Infosys, TCS etc. could continue this trend. This was followed by PI (explained above). Asked him a couple of questions on increasing role of consultants in assisting implementation and talked about the trend at McKinsey.

By this time, I was a robot. This was the best interview of the day for me.

Tips: If you can’t immediately think of established structures, just think-through the logical sequence of events. If you were there in that situation then how would things unfold stepwise? Then within each step, mini- structures/frameworks would readily fit. Again, give examples from work- ex and life beyond work. If you have seen something happen, it has to be true. Also, industry awareness is important to some extent. Reading a Financial Daily for 2 months before the interviews if enough.

Round: Case Study Interview
Experience: In PI, we discussed the scale and infrastructure that Google has and how it’s gaining competitive advantage from it.
I told him searching porn well is very important for a search engine entering a new market, and from there we went into market entry strategies for the search engines.

The PI went on for 20-25 minutes, at which point he realized he had to ask me a case. He asked me a really simple case which got over in 5 minutes

The case was very trivial. It was just multiplying a bunch of numbers together. Less than 5 minutes.




Round: Case Study Interview
Experience: Interviewer also works in IT, so he wanted to discuss what Infosys should do next. We talked about their business model, about billing rates and how they can leverage their assets. I brought up the point of “Centers of Excellence” and how they don’t really work in IT services. He asked why, then asked me to come up with alternatives to the model. I talked a while about a skunk-works type project team that they should set up. We discussed the future of the market etc…

The interview was very conversational. No case really, more of a discussion around what I thought of the IT industry and where I see the future of the industry.


Round: personal interview
Experience: This interview was about 20 minutes long, and it was all PI. He asked about why I did an MBA, what I liked/disliked about working at a place like Google. This interview was very different from the traditional case interviews. He asked me “What would people on the campus say about Aditya Kulkarni?”, “Why consulting when you’re doing so well in Google?” etc… I was very honest with my answers, and didn’t use any of the canned responses. I even said that I’m quite lazy and don’t like doing hard work.
We even discussed strategies to do well at exams without studying for them.

I was very honest and upfront about what I wanted from McKinsey. I didn’t use any of the “prepped” answers, and just told him what I thought. I even told him that I was undecided about joining McKinsey (if they made an offer), and he seemed OK with that.

Round: Case Study Interview
Experience: Case Structure Looked at aspects of
• Motivation
• Compensation
• Opportunities for Growth Solutions structured as short term vs. long term and economic vs. soft factors. I gave many solutions, some which he said they had also thought of, some which he critiqued and some others which he found interesting. He was looking more for ideas than approach – what was being tested was creativity and perspective in tailoring practical solutions. Some of the key points were that you needed to tie the patients/junior staff to hospital and not to doctor – e.g. through brand building, patient management systems, soft loans to junior staff, facilities for families etc. For doctors we could look at involving them in administrative activities, making the hospital an avenue for conferences, publishing papers, involving family etc.
Tips: It pays to be nice to your interviewer and appear interested in the case even if it is from an industry/function that is completely different from your background. Sometimes there is no need to structure cases because the interviewer is more interested in how creative and innovative you can be in deriving solutions.

Round: Case Study Interview
Experience: • I started by asking what kind of hospital it is? It is a hospital focused on tertiary care: cardiac & neurology
• Then I proposed a structure: o Customers & Market o Company o Competitors o Regulation
• Was asked to focus on customers & market • Started segmenting the market – city dwellers, towns, villages
• Wanted to match the offering of the hospital with which customer would need it most and is able and willing to pay
• So tried to setup a matrix of ailments on one side and customer profiles on the other axis.
• Realized that cardiac ailments are more common in cities hence people there are better targets.
• For neurology, understood that it is very expensive hence setting up a hospital in smaller towns may not work well as hard to recover the money. Alternatives exist for towns where they either go locally or come to cities for treatment – its not an emergency treatment so people can plan it.
• At this time the partner stopped the case
Tips: Don’t be daunted if your first interview itself is with a Partner – usually these guys are more relaxed (but that’s just my take)

Round: Case Study Interview
Experience: • This case started out very strangely. It felt just like a question and I suddenly realized I was in a case!
• So I evaluated this from two factors: o Services turnover (attrition, falling $) o Scale
• I also talked about who these guys want to compete with – answer HP, IBM, Accenture
• Then I did a comparison between the Indian IT majors and the likes of HP and one thing that came about was lack of products in IT majors. Also, with Accenture the ability to sign consulting deals and not just services.
• Hence, we started talking about what these companies can do from the perspective of: o Hiring o Acquisitions of products / technologies o Target customer profile o Focus on local players in India that have global ambition like ICICI and take their successes to the world
• At this time the case stopped.
Tips: Be relaxed. Sometimes the interviewer won’t even tell you this is a case. So it’s fine to go with the style of the interviewer and make it conversational.
