Round 2

Other Interview

Interview Experience
The initial interview was known to be Data Structures and algorithms round. The two 
interviewers totally asked me questions on data structures and mostly concentrated on how 
much I knew about time and space complexities.
a) The first question was to find the vertical column sum of every column in a given 
binary tree and return the result in an array from left to right.
The first solution which I told is by finding the leftmost and rightmost index of the array , 
thereby finding the index for the root. Following to this step, the sum can be stored easily while 
traversing from top to bottom and saving the value at index­1 while moving to the left and at 
index + 1 while moving to the left. This solution used two tree traversals. 
 He was good with this solution but asked to optimise with respect to time. Then, i 
shooted out the solution using a doubly linked list where we can traverse to and fro and store all 
the sum values. While using linked list, instead of index ­1 & index + 1 , prev and next pointers 
can be used to access the next and prev location from the current location. This way , the 
solution is optimized with time.
b) The second question was that I have been given a binary tree where the node 
structure would be something like below :
 struct tree
{
       struct tree * left, *right, *sib ;

Now , the task was to point every sib pointer to its nearest rightmost node in the same level. i.e 
the sib pointer of the rightmost node at every level would be NULL.
The first solution which I told them was to perform a Breadth first search and by using a 
queue would connect all the nodes of a level at a time. But, this would increase the space 
complexity and of course I was asked to optimize the solution.
       Given tree :
                                                                  root ­­­>  1
                                                                             /         \
                                                                         2               3
                                                                     /         \              \
                                                                    4       5                 7
     The result should be :
                                          root ­­­>  1
                                                                             /         \
                                                                         2   ­­­­­­>  3
                                                                     /         \              \
                                                                    4 ­­­­­> 5­­­­­­­­>7
  Let me explain the solution which I gave them for the above example. 
          Starting from 1, for any node connect the sib pointer of left node to its right node if both 
are present or if both are not null. If the left node is not present then no need to perform this 
operation but if the right node is alone present, then there may be another possibility for the 
presence of some other nodes at the same level. Here ,  2 will point to 3 as explained above. In 
the same way 4 will connect to 5 . But , we come to know that in the second  level there is one 
more node 3 and it has a child 7 . So , 5 is connected to 3’s right child. In the same way the 
other nodes would be connected. By this approach, we can understand that before pursuing 
towards any level, all the sib pointers in the previous level are connected. This solution would 
work for all the test cases. 
c) Given two arrays of integers , find the intersection of both arrays. I was asked to give 
various solutions and sort the solutions with respect to time complexitiy.
d) Given a binary search tree with positive integers and a number ‘X’ find the next 
greatest number to X from the BST. If the number is not present, return ­1.

 and code for it on paper. The two problems were based on data structures.
a) Given a binary tree, find the ancestor matrix where time complexity was considered 
but not much than the written code.
Given tree :
                                                                  root ­­­>  1
                                                                             /         \
                                                                         2               3
                                                                     /         \              \
                                                                    4       5                 6
The ancestor matrix is shown as 
     1   2   3   4   5   6  
1   0   1   1   1   1   1   
2   0   0   0   1   1   0
3   0   0   0   0   0   1
4   0   0   0   0   0   0
5   0   0   0   0   0   0
6   0   0   0   0   0   0
Let the above matrix would m[][]  such that m[i][j] = 1 , where i is the ancestor of j.
b) The second question was to swap every consecutive two nodes in a singly linked list.
         For example given a list 1­2­3­4­5­6­7­null
         The result must be      2­1­4­3­6­5­7­ null
For the above both questions , the interviewer saw the code and reviewed it with 
different test cases to get satisfied.                              
Round 4

Hr cum technical

Interview Experience
This was a HR cum technical round, but most of the questions were straight forward. 
The two managers who interviewed me were testing my managerial skillls. Lot of questions 
arised and the interview went for more than a hour. Few questions were like :
a) What do you know about Amazon ?
b) Why I preferred Amazon.com to my previous offer ?
c) The responsibilites which I undertook during my college days with brief explanations 
on every responsible task which I did !!
d) Any projects which I did apart from academics ?? I explained about my android 
project which I did with my elder brother.
At the end the round ended with a simple technical question =>
      I was asked to design a stack using a c++ class such that it can perform the following 
functions which will be called by different APIs :
            ­ Create a stack of size ‘n’
­ Push an element into the stack
­ Pop an element from the stack
­ Destroy the stack 
     At the end of this round, I asked about their experiences at Amazon.com and about my 
work/role at amazon in future.
Round 5

Technical Interview

Interview Experience
Coming to the fourth round, it was totally technical. Technical here covers theortical topic 
from the fields of Operating systems, OOPS and Networks. The questions which were asked 
were :
a) What is the difference between physical address and virtual address ?
b) What is page table and paging ?
c) What is the difference between thread and process ?
d) What is context switch and how it differs between process and threads ?
e) What are threads and why are threads preferred to process ?
f) What are semaphores and differnce between semaphores and locks ??
g) What are the 7 OSI layers in networks and their functionalities ?? He mostly asked 
about transport and network layers.
h) What is encapsulation ?
i) What is polymorphism and their types ??
j) What is differnce between polymorphism and function overloading ??
k) The last question was to design / implement a singleton class .
Here this round ended, but I made many sothapals without sufficient preparation :P
Interview No ­5
 This interview was also HR cum technical round but it was known as a bar raiser round. 
I am not sure how to spell it too. The questions were almost the same as in the 3rd interview 
with additional questions like  “ how did you react in conflicting situations in four year career ? “.
This round also ended with technical questions :
a) Given a doubly linked list where the next pointer is pointed to the next node in 
that list but the previous pointer is pointing to any random node. I was asked to make a 
similar list efficiently . [ Simply a xerox of it ]
b) The second question was a string based traversing and pattern matting type 
where there were given two strings ‘A’ and ‘B’. 
I was asked to return true if all the characters in ‘B’ were present in ‘A’ or else 
return false. I explain many solutions in which he asked me to code for a particular 
solution and he verified the code by iterating though the test cases. 
The round ended with few personal questions on experience and my future role. So, I was into 
Amazon after a week of discussions

Round 1

Case Study Interview

Interview Questions
  • Question 1: Case statement: If you have to merge two companies what will you look at?( Case Type: M&A)
  • Question 2: Tell me about yourself
  • Question 3: Why consulting?
  • Question 4: What are your strength
Interview Experience
Case Details:
Wrote the formula as Company A’s value + Revenue synergy + Cost synergy – Loss in Shareholder’s value. He was impressed by the detailed formula and then we discussed about all of the points we had written. I further broke down revenue and cost synergy into financial and operation synergies and mentioned about how these synergies can be realized.
Interview Tips
Take your electives seriously. Call a few alums in case you need help. Please do take CCMA (Term 6) and MGSP (Term 6). These courses will make all the M&A cases a walk in the park for you. Other than this I found LSCM (Term 6), ECSG (Term 7) and ATAM (Term 7) very useful. Term 5 for me was a disaster because I didn’t consult with any alum and ended up taking most of the irrelevant courses.
Round 2

personal interview and case study

Interview Experience
Personal Interview:
This was by far the best interview I had. The interviewer was a lot of fun to talk to and we immediately connected with each other. He said that we will do a case first and then the PI. Once the cases were over we started with PI.
1) Tell me one reason why you will not join BCG?
I told him that people are great and that is why BCG was my top priority but BCG did not have as big a brand as one of its competitors. Then he went on to explain how BCG has the same brand value in the eyes of senior management of most of the top firms in the world.
2) Tell me three reasons why we should not hire you?
He was smiling when asking this question and told me he knows the question is not fair. It’s very important to reciprocate the way the interviewer is behaving. I also smiled back and said I do not have any consulting experience. If you find people with that experience you should hire him. Both of us laughed at the answer and then he asked me about a genuine weakness. I said procrastination and how I had to go and work in the SantaCruz office during Mumbai terrorist attacks because of this habit and what I was doing to overcome this problem.

Case Statement:
A conglomerate is trying to open another company in IT sector. Tell me what are the things the conglomerate should give to this company and what are the things it should not give? He also asked to tell him how should the firm ramp up its operations? (Case Type:Expansion Strategy )

Case Details:
I asked him what was the aim behind the decision to open an IT arm and he revealed that it was the company believes IT sector will be profitable in the future. He also told me that the conglomerate is aiming to reach a turnover of $400mn by the end of the five years. I asked him about the size of the conglomerate and he said I can assume somewhere close to $40bn. I decided to solve the case using the profitability framework and told him that I will look at what contribution can the conglomerate make on increasing the revenues and decreasing the cost of the IT firm.
He (interviewer) was fine with this structure. Thereafter I started by talking about revenues and wrote revenue = num of projects * avg hrs per project * price/hr. For increasing the number of projects we should do the following:
1. Internal projects. Since the firm is valued at $40bn I assumed that it will have about $400mn worth of IT projects internally and
hence the target can be achieved by giving only the internal projects. However I also said that the conglomerate should not give all the internal projects to the new IT firm and should continue outsourcing some of the critical projects for the next few
years at least. He then asked me should all the internal projects eventually be given to the new company. I told him that different projects require different expertise and hence a new expertise should be developed only if we can get more projects on that particular expertise. He was visibly impressed with this answer.
2. Brand name. I said that the biggest advantage which the conglomerate had over other new IT firms was the brand name associated. I made the assumption that since it’s a big conglomerate it has a good reputation in the market and it can leverage it to get a lot of internal as well as external projects.
3. Relationship. I also told him that the conglomerate will have good relations with number of other big players in India as well as
internationally. We can leverage these relationships to get more projects. I made an assumption that we cannot make an impact on avg hrs per project. However we can charge a premium on price/hr since we have a strong brand associated with us. On the cost front I told him that the primary spending in cost will be
1. Direct Labor (S/W engineers, Project Managers): I told him that brand should help in this recruitment as well since brand is one of the biggest non monetary motivators for employees. Besides the firm should already have some IT engineers in their current firms. They can transfer them to this firm. This will give the IT engineers higher satisfaction as it will give them an opportunity to work on different projects.
2. Sales: Since the firm is an IT Conglomerate it should have a brilliant sales team. The firm can transfer some of their best sales guys to the new firm initially to rope in more customers.
3. Administrative (Finance/HR): In this case I told him that the firm should not give the new IT firm its HR/admin team but hire a new team. This was the case since IT is very different from conventional sectors and hence the culture is different and hence
HR and management team should be radically different from other firms.
4. Power: Probably some subsidy can be obtained from the government.
5. Infrastructure (Rent, Laptops, Computers etc.): The conglomerate might have some land available and can lease out the land to the new firm at a cheaper rate. After this he asked me to tell him how should the sales look like in the next few years and how will that impact their hiring plans. He asked me to predict sales in 6, 12, 24, 36 and 60 months. I wrote a GP series and said that sales would keep increasing exponentially. Hence if the firm wants $400mn in 60 months they should get $200M in 36, $100M in 24 and $50M in 1 year. He smiled and told me what’s wrong with this. I immediately corrected my mistake and told him that it will be $200M in 4 yrs, $100 in 3 yrs and so on. Then he asked me what might go wrong with these projections. I told him that what may be wrong is the growth of 100% at the end of 60 months. Hence may be the growth will slow down and hence the growth in sales might be 100% in first two years, 50% in the next two years and 25% in the final year. He was fine with this answer and then we went forward with PI.
Interview Tips
Do not neglect PI. I was asked why we should not hire you in my DB interview in November. I screwed it up badly because I never expected that question. But during my consulting interviews I was ready for this question and it helped. Make a list of at least 50 questions which can be asked in PI interviews and write brief bullet points for each question. Do not mug up the answer but practice each question at least 3 times in front of the mirror.
Round 3

personal interview

Interview Experience
This was my 13th interview of the day but looking at the interviewer I was sure it was his 13th or 14th as well. However I had got an offer from Booz and hence was upbeat and confident. There was no case in this round which was a bit strange. However we talked for more than 15 minutes. I do not remember all the questions but they varied from mugged up questions like why consulting to questions about my family. He even asked me that since I plan to get married as soon as I join consulting how is my wife going to take it. On this I replied that she has told me that I can work as much as I want on weekdays but weekends are for her. Hearing this
he smiled for the first time in the interview and said good that she already understands this . After this we had some discussion on
telecom sector since I decided to talk to him as to where does he think the price war in the sector is heading towards.
Interview Tips
During the entire interview the interviewer looked disinterested. He was looking down, at my CV, wasn’t maintaining eye contact and asking random questions. However I decided to remain upbeat and kept answering with confidence and a smile on my face. This helped me in maintaining the pace of the interview and he did smile back eventually at one of my answers. In spite of this being the 13th interview I was able to achieve this because I had got into the habit of solving 4-5 cases in a day. Hence start practicing cases on a stretch and do take mockathons organized by consulting club very seriously. Besides remember to keep the mood
upbeat at all the time no matter how your previous interviews have gone and no matter how tired you are.
Round 4

Case Study Interview

Interview Questions
  • Question 1: There is a cement company which is interested in increasing their profit/kg. How should they go about doing this?(Case Type: Profitability)
Interview Experience
Case Details:
Asked him why they are interested in profit/kg and he told me to think what might be the reason. Told him that the amount they can produce is limited and hence might their profits are maximized if their profit/kg is
maximized. After this I wrote profit/kg = Price – VC – FC/kg. Since cement is a commodity we cannot affect the price a lot. At this he told me that is it impossible to increase the average price for the company. On hearing this I asked him about the markets we serve and does each market have different price. He also told me that was indeed the case and the prices were higher in certain regions of India and lower in other regions. I asked him why and he told me to think. I could not come up with an answer so he asked me to look at the cost. I broke VC to Direct Material, Direct Labor and transportation cost. It then struck me that transportation cost will be different for different regions and hence prices in those regions will be different. On hearing this he smiled and told me how we can then help our firm optimize. After this I wrote the standard DMOP supply demand optimization
problem and he was happy with the answer. But then he asked me to think if we change supply in a region what will happen. I drew the supply demand curve and told him that price will go down. He told me how I can represent the graph in the optimization equation. I could not think of anything and then he replied back telling me that we will include the price elasticity for cement in each region in the equation as well. After this he told me to think of competitive response. I told him that we can solve the optimization equation for the entire industry and try optimize for the entire industry. He liked the solution but asked me what else we can do if we do not know about the exact cost of all our competitors. Then I drew up a 2 X 2 with one axis being our variable cost in a region vs. our competitors’ variable cost.
He told me to think in terms of strength of competitors as well and I told him we should increase supply in regions where strong regional players are not there since the regional players cannot reduce the supply in a region but the national player can reduce supply in this region and increase supply elsewhere. He then asked me what may go wrong. I told him that if we do not communicate our strategy well than we may get into a price war in the entire country with the national player and this might lead to a bigger problem. On hearing this he was satisfied and told me if I had some questions for him.
Interview Tips
Read all the core term courses well. I never thought a DMOP problem might be asked in the case study and it was and hence you should have good control of all the core term courses. Also revise Economics properly since a large number of cases can be solved if you can think in terms of demand and supply properly. Besides in the interview do not try to judge yourself. In this interview I was not able to answer about the elasticity bit but I did not lose my confidence and excelled later in analyzing the competitive response.

Round 1

Case Study Interview

Interview Questions
  • Question 1: Biscuit manufacturer- higher costs vs. competition(Case Type: Profitability/ Costs)
  • Question 2: Tell me about yourself
Interview Experience
Case Details:
Asked questions to understand more about the company. How many centers/ factories there were and if there was a cost issue in all of them or just one. He said it’s common across the board. I asked the unit of measurement- it was 100gm of biscuits. I then went on to break the costs down into Fixed and Variable Costs as follows:
Variable Costs:
• Material: Flour/ Sugar/ Other
• Labor: Labor Rate * Hrs/ 100gm (Productivity * Wage Rate)
• Variable Overheads
Fixed Costs: Rent/ SG&A/ Utilities/ Depreciation. He said it came to $6/ unit including fixed costs and variable costs but
competitors had $4/ unit. I then went on to understand the product a little more and if we produced the same type of biscuits as the competitor. He said we produced glucose biscuits (commoditized market) and premium-quality biscuits. Glucose biscuits costed 4.5/ unit and premium biscuits costed 6.5/ unit. At this point, I asked some more questions and learned that this firm produced a higher share of premium biscuits and charged 6/ unit for glucose and 7.5/ unit for premium biscuits.
I analyzed the numbers quickly to say that more than 50% of the production were premium biscuits, given that the average was 6- closer to the 6.5 than to the 4.5 unit cost.
• Summarizing inferences thus far I said that two issues, before we go forward seem to be The 4/ unit and 6/ unit comparison were not apples to apples, since the products and corresponding prices charged were different
• The glucose biscuit itself is produced at 4.5/ unit vs. competitors’ 4/unit –which I said I would investigate in detail now
We went into the details of Fixed and variable costs again
• VC: flour (material) costs were higher because the flour cost and packaging cost was higher. I also checked off the possibility of any additional flavors used that could cause an increase in material costs.
• FC: Factory related fixed costs i.e. depreciation and lease expenses were higher I then summarized all three aspects of the case and wrapped it up
Laid out an all comprehensive structure upfront. That made the interviewer comfortable that I would cover all points ultimately. Was very relaxed and comfortable- and picked up hints all the way- I think that was very useful.
Interview Tips
As everyone would probably say, keep your structure as ‘MECE’ as possible. Feel comfortable and go over each point step by step!
Round 2

Case Study Interview

Interview Questions
  • Question 1: Mines- costs case(Case Type: Profitability/ Costs)
  • Question 2: The client is a metal mining company that mines ores, smelts and refines it and draws wires out of it. 3 rd player in the market with 10% market share. Not doing well for over 40 years but last 1.5 years profits seem up because of an increase in price from international market tariff rates.
Interview Experience
Case Details:
We need to look over why the company has not been doing well in the past first and then analyze the impact of the prices on the profit improvement and if the company has done anything to improve profits other than the price rise. Through discussion we figured the company had not done anything to change the way it operated. So clearly, the price was the only temporary savior –and we needed to look more closely at the costs. I used the profitability framework through understanding the value chain. Asked about the end product, if it was differentiated (no!) and the customers (auto/ industrial manufacturers/ construction industries et al)
I laid out the cost structure –labor/ productivity/ labor rates, materials issues- quality of materials, wastage, bargaining power and hence rates with suppliers, fuel costs- unit costs, sourcing, quality of fuel, efficiency/ utilization. I then went over to the fixed costs: rents/ equipment/ depreciation/ SG&A/ logistics and supply chain costs. The one thing I thought I mentioned (from my previous interview) but didn’t is the SCALE of operation.
Laid out an all comprehensive structure upfront save one point (that I thought I’d mentioned, since it came up in the previous interview). I had an amazingly good connect with the interviewer, stemming from striking a rapport during the dinner
Make sure you start on a clean slate, after your previous interview. One thing I did-like stated above- was to think I mentioned ‘scale’, as I had gone over it in my previous interview moments ago. Fortunately, I told the interviewer that very honestly and he saw the point!
Interview Tips
Leverage the dinner and every interaction point with the company to build a rapport and understand more about the firm- and demonstrate your fit for it
Round 3

Case Study Interview

Interview Questions
  • Question 1: Supply Chain Streamlining: TV Manufacturer with an inefficient supply chain- come to us for advice(Case Type: Operations/ costs)
  • Question 2: Tell me about yourself
  • Question 3: Why is your GPA what it is?
  • Question 4: What drives you?
  • Question 5: About my musical background and interest, the band in undergrad that I had started et al. –in short, a quick snapshot of my story thus far!
Interview Experience
Case Details:
Had a first moment of panic since I have had NOTHING to do with supply chain management, be it at work or through coursework. So, started off with first principles and tried to work with the interviewer to understand the mechanics. Started off with asking the following questions:
• What inefficient meant- quantified as costs of supply chain process
• About the TV manufacturer: type of products (generic product)
• About the firm’s market position: market leader (15-20 years)
I laid out the supply chain; suppliers through to firm to distributors. At this point, interviewer asked me to focus on the dealer/ distributor side. I asked about the dealers: own retail stores/ local dealers –and was told that it was local dealers. I started asking about the dealer margins(yikes) when interviewer told me to take a minute and grab a drink of coffee before proceeding! . Thank God for that. I then went back and said I wanted to look at where the end customers where (all over India, uniform distribution), where the current distribution centers were (Chennai, Pune, Nasik and Delhi). I also broke down the costs into (i) transportation (ii) shipment (iii) packaging. At this point, I drew a quadrant and said that there was a mismatch with 2 centers in the west, none in the east and one up north and one down south, indicating that we’d be spending more than required on the
distances covered. I then went into the modes of transportation- (i) road (ii) rail (iii) air (iv) ship , explaining the pros and cons of each and further broke down the costs into “sort-of” variable and fixed, once interviewer asked me to focus on the ‘road’ route.
• Fixed: Equipment –Own/ Rental (in which case a lease rent would be paid).Fuel costs/ equipment (depending on how the company charged these costs)
• Variable Costs- Packaging costs (LCD TVs would require more packaging than normal TVs- so I wanted to rule out the possibility of disproportionate allocation)
Zeroing on the equipment costs, per Vikas’(Interviewer) hint, I broke down the costs into loading/ unloading/ on-the-move (fuel: quality, mileage, efficiency)/ storage costs, especially given the distances involved. I also asked about the size of the trucks. Clearly bigger trucks were used with less utilization –and that clinched the close of the case.
I approached the case based on first principles, especially given I had no background or coursework in supply chain, and kept the interviewer engaged in the discussion by constantly thinking aloud and picking up hints.
I jumped in a wee bit quickly on to the case initially, at which point the interviewer asked me to pick up some coffee and think for a bit . So, maybe I shouldn’t have let my excitement get to me!
Interview Tips
Be comfortable and avoid getting frazzled or excited if the case is something out of your expertise/ experience/ coursework radar
Round 4

Case Study Interview

Interview Questions
  • Question 1: PE Fund acquiring Italian company:An Indian PE Fund is looking to acquire an automotive firm in Italy and they have come to you for advice.(Case Type: Acquisition/ LBO)
  • Question 2: Tell me about your work experience.
Interview Experience
Interviewer had done a lot of work with private-equity clients and wanted to hear about my private-equity turnaround experience in detail.
Case Details:
I would like to understand three pieces of the story first- (i) The PE Firm, the industries it usually invests in, the size of investments, required IRR (ii) The Automotive Firm- what products/ services it produces, product differentiation, market position. (iii) Any overarching reason/ objective why the PE Firm was looking to acquire this firm.
The interviewer asked, (i) Size-wise, the PE Firm invests in all size firms, industry agnostic and requires a 25-35% IRR (ii) The company manufactures high quality, high technology end-gears and has a market share of 20-30% with the immediate next competitor having 5-10% (iii) No overarching reason –what could be the reasons, do you think? I laid out a framework talking about
a. Attractiveness of the company, growth/ IRR
b. Access to the Italian industry for the PE Firm, towards other strategic interests –maybe getting into a different company through starting here
c. Being an LBO, easier availability/ better terms of debt in Italy since private equity players amplify their returns primarily through debt
d. Any benefits for the PE Fund’s current portfolio companies in India courtesy the Italian association
e. Any domain-specific expertise the PE Fund could bring to the company
f. Any of the PE partners being Italian thus having a leverage there
g. + Other factors I spoke about, that I’m unable to recall now! For each I laid out the typical acquisition framework around market/
industry analysis, other factors, profitability and added the PE perspective to it.
I used my learning from my work experience and the ‘Investing in Private Equity’ course to go over (i) What a PE fund looks at (ii) Basic Acquisition frameworks (iii) Factors governing an LBO . This interview also took a ‘discussion’ form where I also got a chance to ask interviewer what the real situation was and why the Italian firm was acquired, since it was a live case
Nothing much here . I enjoyed the case, given it was on PE’s and was thrilled to use my INPE course concepts therein!

Application
I was interviewed on-campus for NA role at Booz & Company
Interview Process
Case Study Interview PI and Case study HR Interview
Round 1

Case Study Interview

Interview Questions
  • Question 1: Improving performance of two retail stores
  • Question 2: There are two companies one with 50% equity and other with 60% equity and rest debt. Everything else being same, what would be the difference in cost of capital of the companies.
Interview Experience
The interviewer started “tell me about yourself” while he was reading through the resume.
Case Details:
Then the interviewer asked about a particular bullet point in resume. The question given as case study was based on this.
For the next 15-20 minutes, we spoke about the measures taken to improve the performance. We went into exhaustive discussions
about the steps taken and what else could have been done. We discussed about product mix, the performance of other stores in the
region, agricultural potential of the area, means to attract customers etc.
For the next question, I asked about the tax rate and he said the tax rate is zero. I gave the answer.
He then asked me if I wanted to ask something about the job. I asked him about his career progression. I also asked that Booz being relatively new entrant in India, how it was planning to expand.
The detailed discussion on resume point went well. I was also pretty relaxed during the interview which helped.
While giving answer for the WACC question, I simply gave an answer and did not illustrate the logic of it. I could have taken him through the logic.
Interview Tips
Typically we prepare a 3-4 minute pitch for each resume point. In my case the discussion on a single point went for about 20 minutes. So it’s important to know your resume very well and talk about it convincingly.
Round 2

PI and Case study

Interview Experience
: Tell me something about yourself (went on for about 4 minutes as he did not stop me and expected more)
: What are the qualities required to be a successful consultant
: Why do you think you would make a good consultant
: What other career choices are you looking at. Which other firms are you interviewing with.
: What are your long term career goals. How would you achieve them.
: While discussing my experience in KPMG audit, the discussion veered towards corporate governance. So he asked me to tell
what went wrong with Enron – the question stumped me because I had not expected it and had last read about Enron more than 5
years back. I gave him a rough sketch about how Enron managed to cook its books.
The personal interview lasted for about 15-20 minutes. Generally there were follow up questions to what I answered. Then we started with a case.
Case question: An oil marketing company wants to launch a fuel card where the customer can pay through the card and settle the bills at the end of the month. Users would also get loyalty points. How would you advise the company on whether they should undertake the project.
Case Details:
I started with broadly stating that the considerations would be strategic, financial to see if the project is viable and then operational to see if it can be implemented. To see whether we would have any strategic advantage over competition with fuel card launch, I explored the potential customers.
S(me): Has any competitor launched fuel cards or any similar program of their own?
P(interviewer): No. Ours is the first company considering its launch.
S: To see whether customers would value fuel cards, let’s categorize the customers. One set who would value it would be transport service operators. Other set would be retail customers who would appreciate the convenience offered by fuel cards and loyalty points. The points would also help in creating a customer lock-in.
P: That covers practically everybody. Why would transport service operators value fuel card ?
S: It would mean drivers would not need to carry cash with them on trips and hence greatly reduce operational hassles. There will be decrease in leakage/theft as the drivers would be paying directly by cards. Operators would have transaction ease in paying at the end of month and also greater control over the fuel usage. Interviewer seemed happy with the reasons. I said that there seemed to be a market for fuel cards and by implementing it, we would be able to increase our sales by eating into our competitor’s pie. We proceeded to check the financial viability. To check the financial feasibility I outlined the following scheme: Incremental contribution due to fuel cards Implementation and operating costs for the same Hit in margin if we do not implement and some competitor implements the same
I checked with interviewer if he was ok with the overall approach and he said fine.
S: To compute the incremental contribution, we need the current sales level and the margin level
P: Current sales are 100 mn lts. Margin is 10 cents per ltr
S: We would need the competitive scenario, number of stores and incremental sales expected at each store to estimate incremental margin
P: Assume there is an overall 30% increase in sales volume
I thus calculated the incremental contribution. We then proceeded to calculate the cost of implementation and operation.
S: Operating costs would depend on the model of operation. We can either tie up with a bank and they can take over all the back-end like and operate it like credit card operations. Else we can have our own set-up and generate bills for the customers. In our own set-up, there will be higher set-up costs and interest foregone for credit period. In tie-up with bank, we would have credit card charges as normally levied by the banks which are generally around 1.5% and maybe some additional operating costs. Other than that, we would have incremental costs at the pump level like a telephone line for card usage. Interviewer gave me a fixed cost per month which was same for both scheme and included depreciation etc. This certainly made life easy 
S: What are the loyalty points costing us?
P: 3 cents per ltr
S: When we launch fuel cards, the card sale would also poach into our cash sale. Hence though the overall incremental sale is 30%, what is card sale as a % of total sale?
P: cash and card sales are 50% each.
I then worked out the numbers to determine that launching fuel cards was leading to financial loss on a standalone basis. I then asked whether we should proceed to compute the potential loss in revenue in case we do not launch fuel cards but a competitor launches it. The interviewer asked me to summarize the case there. I said that fuel cards seem to have a good market but is leading to a loss on standalone basis. To take a decision, we need to see potential loss if we do not launch and a competitor launches the same. Also, we could look into reducing loyalty points as it’s a major cost head. We are delivering real value to customer and current scheme may not be required.
Prep for personal questions helped me in the first half. Case went well in a structured manner.
To conclude, what I think went wrong with the interview was the Enron question surprised me and I did not give a very good answer. But I guess there can always be surprise questions. Having a fair idea in the field of prior experience would help.
Round 3

HR Interview

Interview Questions
  • Question 1: How many interviews you gave in the day.
  • Question 2: Tell me about yourself question.
Interview Experience
We did not discuss any case during the interview. However, we spoke on length about my work experience and learnings. I had worked in rural retail business and rural marketing business in ITC before joining ISB. So we went into a lengthy discussion about rural India and its potential. He asked whether the buzz surrounding rural India was justified. I gave my opinion. He then asked what were the hurdles in rural India and what were the factors determining success. I gave examples from my experience and listed down the hurdles and success factors. We discussed them in details and he came up with a sort of matrix to evaluate the potential for rural success based on factors discussed. I also highlighted the importance of right product which can make a big difference and gave some examples in this regard. I also listed down the key drivers for business in retailing business in rural
India.
After some more questions, the interview ended.
What I think went right in the interview is that I was able to talk about my experience of rural India in both retailing and marketing businesses in detail with numbers and examples which made the discussion more lively and believable.
Interview Tips
Again knowing about your work experience thoroughly helps.

Interview Process
Test Technical Interview
Round 1

Test

Test Sections
  • Section 1: Algorithms
Interview Experience
1.    Queue in O(1)  solution.. I came up with a method and it was not the most optimal one… 
and I asked if I should optimize more.. he said he was happy with the solution I gave and 
proceeded to the next question…
2.       For eg.. if there is a string abda. I shud reverse it n/2 times.. ie… say
1st rev: adba
2nd rev: (during the second reversal I shouldnot rev from beg.. but rev the string between ( i+1,j­
1) where i=0,j=n­1in the first case….)ie
a db a => a bd a….
so it is abda finally….after n/2 reversal we get the initial string which is abda.. this is a 
favourable case and I increment the count by 1…
The question is give the string length say n=4 how do u find out the total number of strings 
which will have the favourable condition after n/2 reversals…. I came up with a solution… just 
think over it.. not a difficult one… just 5mins of thinking will get u reach the right answer….
3.    There are 100 petrol pumps between two points A and B/.. u have to select 10(say) petrol 
pumps such that the largest distance between any two petrol pumps should be minimum…I gave 
a top down approach.. guess he expected a bottom up approach….  But at the end he was quite 
happy with my answer…
4. tel me a scenario where i cud use MERGE SORT AND QUICK SORT AND WHERE I CAN 
USE ONE NOT THE OTHER.. and the differences...
MERGE SORT:
when there is 1GB of things to be solved we can divide that 1 GB into A*B=1GB , such that 
each division will have a size of A(MBs)... in this case I cannot bring the entire 1GB into 
memory.. So i ll bring A(MB) into memory at a time sort it and keep it and sort all the B 
divisions and do a B­WAY Merge... which will be easier... But this kinda thing cant be done in 
quick sort...
Quick SORT:
if we want to find the Kth smallest v can use quick sort without sorting the entire array but its 
enuogh.. till the pivot element is placed at the kth position... (random select...)...... this cant be 
applied for merge sort..where v have to sort the entire thick to identify.. kth smallest...
Round 2

Technical Interview

Interview Experience
This round involved all concepts right from OS, DBMS, Networks, Data structure, Algorithms, your 
projects,  a slight touch on testing…
Topics covered in each subject:
OS: Threads, process… difference.. if threads have more advantages y go for process??
Semaphores, Synchronization, concurrency problems, Second chance algorithm in virtual 
memory chapter….
DBMS: Second highest salary… TRY TO USE TOP… I TOLD HIM TWO SOLUTIONS ONE 
WITH TOP AND OTHER WITHOUT TOP … But he emphasized me to use TOP first.. So use 
that…
He gave me a set of tables and asked me write queries
Indexing was also an important concept he asked me.. B+ trees properties and how used in DB.
Normalization of my tables in my project….
Data structures:
Difference between binary trees,  hash map, Tries.
A scenario where BST has advantages than hash map without any collision.
How do we avoid collision in hash
Example of a good hash being used…(I told STL..he said no that’s a different concept.. I then 
said…Java hash map…..that was the right answer… time for getting.. most of the time O(1) and 
depending on the inputs and the things it might vary accordingly )
Tries advantages and wen can it be used….and application of it..
Networks:
Layers of OSi.. explanation of each layer 
Google.com steps involved
About DNS
Testing:
What do u know about testing…
I explained back and white box testing… alpha n beta testing.. and he said..he was  not proficient 
in it..n stopped…
Algorithms: (besides the algorithm round)
Difference in greedy n dynamic… which is better….
Kinda company oriented questions:
advantages and disadvantages of that site…
what I know About Advertising online…

Interview Process
Case Study Interview Case Study Interview Case Study Interview
Round 1

Case Study Interview

Interview Questions
  • Question 1: Case Study Type: Data Interpretation
  • Question 2: PI Questions: Why were you promoted twice before the actual tenure? Can you give some specific reasons?
  • Question 3: Why did you quit TCS? Would you join TCS back if you were made an offer? Why/Why Not?
  • Question 4: What is one thing that you felt you did not handle well in your work experience? What would you do different now?
  • Question 5: Do you have any questions?
Interview Experience
Case Details:
It’s a data and graphs based case covering all the fundamental concepts of marketing viz., market sizing, sales force sizing, etc.
Wherever there was ambiguity in the case, I asked questions and got clarity on what exactly is expected as the answer? I have worked out every step of the calculations for quantitative questions thus involving the interviewers through the problem-solving process. For one of the questions, I missed the foot notes given in the slide and asked a question that would have otherwise not arisen.
Interview Tips
Be clear with the marketing fundamentals (courses 101 & 102) and be ready to do some calculations (simple though) and data interpretation The case and questions are relatively simple and quite solvable on the spot. So, just keep your cool and focus.
Round 2

Case Study Interview

Interview Questions
  • Question 1: Multiple
Interview Experience
Case Details:
I was given around 15 documents (~45 pages) related to an ice cream company and 40 mins to understand those documents and come up with a presentation on flip charts for two of the board of directors of the ice cream company. There were detailed questions from the two panelists during the presentation on the understanding and the recommendations. I have followed the 4c-4p framework approach for solving the case and thus could systematically take the panelists through the presentation. I could remember some important details in the documents and cited
the appropriate numbers while explaining my problem analysis and defending my recommendations. One of the panelists looked disinterested after listening to the presentation which gave an impression that my case understanding is wrong but I tried to stay focused and positive about my case analysis. I could not manage my time on the case preparation really well and came up with minimal details on the flip charts. I was mostly explaining the numbers while talking through the presentation. I could not answer some of the questions asked by the panelists.
Interview Tips
Distribute your time wisely for case analysis and presentation, you have to be prepared to get on to the case really quickly. The amount of data in the given time frame is overwhelming. So, it is
important to stay cool and focused. The interviewing panel is very pa
Round 3

  • Question 7: Have you encountered any difficult team member? How did you handle the situation?
  • Question 8: You seem to be a very soft spoken person? How do you handle arguments/disagreements during meetings or how do you make your voice heard in tough situations?
Interview Experience
Was consistent in my answers for PI questions right from Round 1
Interview Tips
In my opinion, there are no right/wrong answers in this round. This is basically a psychometric assessment to check the team fit. If you made it here, you are mostly in
