Bain & Company Business Analyst Intern Interview Questions and Answers

Round: HR Interview
Experience: They had 4 interviews.
McK1: Have faint recollections. However I remember I did well on the case and had loadsa HR involved specially in my work on internships and research paper.

Round: Technical Interview
Experience: McK2: The interviewer was a PhD in Chem Engg from Stanford followed by an MBA from Harvard. I found this before going in and got real nervous. He started off with some Chemical Engg questions and soon realized it was no use! (He did even comment that I had not learnt anything in Chem engg in the 4 years). We then moved on a case of petrochemical industry where a new player wanted to enter an oversaturated market. I concluded that scale is important and the entry has to be below the existing market price. Some HR including my question to him. Had a long discussion on Foreign MBA vs Indian MBA. At the end of the interview, I guess I had done a good enough job (surprisingly after the start I had) and was called in for the next 2 interviews..

Round: Case Study Interview
Experience: McK3: This was a disaster! And a big one. I was given an extremely easy case on nuclear reactor vs coal reactor economics. Simple mathematics which I screwed up because of just 1 simple error. I realized the same pretty late and pointed it out. He said it was ok. No HR

Round: Other Interview
Experience: McK4: The whole interview was a discussion on my BTP and seminar. BTP was related to Phosphoric Acid production. The discussion revolved around whether phosphoric acid should be produced in India or whether we should produce it outside from where we import ore. Then we moved on to my seminar which was related to Kyoto Protocol. Finally I asked question on how different is a foreign MBA vis a vis an Indian one. Very peaceful and fun interview!
Tips: The single biggest mistake I committed was going in a haste into the McK 3rd interview. I got involved in some placement work between the interviews and forgot to carry my folder or even a pen. This is probably why I did not do well on the case (which was probably the easiest of all 8). Its very important that you take 5 minutes off before walking in, get your composure and stop worrying about other things and just attend to the interview on hand. Key learnings included the fact that it is relatively difficult to come back if you don't start well. Thus its is better to take something like 5 seconds before you answer the first 2-3 questions to recollect thoughts, organize them and frame them well. Also that you need to be comfortable with everything on your resume. I appeared for 8 interviews and never mentioned/was asked anything related to MI which I thought was the most important point on my resume. Instead I was questioned on my hobbies. Smallest points on the resume could be the ones you are grilled most on. Another very important thing about case interviews is the fact that the interviewer will be guiding you all through to the final solution. Any thing that he speaks should be heard and taken notice of. Most of the times there will be a small hint given at some point and all you need to do is catch on to it! Structuring your answers is extremely important. One more important thing to keep in mind is that all your answers should kind of show to the company that you can FIT into the company, the job and the culture. It is also important you walk in with the feeling that you can get the job. Specifically in cases, if you get stuck, take some time off to think. Structure your solution well, it carries the maximum weight.

General Tips: Firstly suit up only in case you are comfortable in it. It makes no sense to wear it and be uncomfortable throughout. And in my opinion even if you do not wear one, it never goes against you (at least consulting). For companies like FMCG/Tech its better not to suit up because it doesn't go with the company cultures. If its IBanking, it is good if you wear one. It is very important that you have some questions for the interviewer for any given company. And it is more important that the questions are intelligent and genuine. Attending PPT/ reading up website is a must for the same. Most importantly you should not talk to any other candidate on interview experience before your interview. The interview changes for every candidate. If say for example you hear the case beforehand, the company is bound to find out which would ruin your chances for sure. Further talking to people who have already appeared increases the nervousness. Posture is something that you have to take care of. People have a tendency to relax which should not be the case. You should seem eager for both the interview and the job. While answering any question the most important things to keep in mind are • Take 5 seconds off before venturing into any answer. Compose your thoughts real well. Then start. Its better to get the whole thing in a impactful way then to miss out on certain points. It also doubles up as giving the interview a feel that you are thinking before answering.

Round: Interview
Experience: There were four interviews, with a case study and some HR questions in each. 
The first interviewer was an IIT Delhi alumnus and asked me a case on whether a telecom company should go for exploring the 3G license option. He provided me with information as and when I asked for it. Later during the interview, I asked him about his experience with McKinsey. 
The second interview involved a case on acquiring land for a B-School. The case was mainly qualitative and the HR questions were also straightforward. Giving a thought to goals and aspirations helped. 
My third interview was with a partner. Again, standard PI questions: something about yourself, why consulting, what if not McKinsey, important attributes of a good leader, why should we hire you etc. The case was on the design on entry and exit gates for Delhi Metro. 
My final interview was again with a partner and there was no HR part. It started with a case, and then there was nothing else to discuss. Anything and everything that could possibly go wrong did. I did badly in the case and towards the end made errors with simple calculations as well.
Tips: It is important to think on your feet even if you are not able to make much headway with the case. This case had sealed my fate.

General Tips: Most of the times, things go on as they are supposed to, we do what we are assigned, meet deadlines and get it over with. Knowing what to do after four or five years of study at IIT is one of those deciding phases where we have to do something out of routine, think about what we actually want, what we can get from where we are. 
Here is an account of how I went about making my decisions and preparing for it. In one of those routine placement talks, a speaker remarked, ‘there are two ways you can choose a career- by extrapolation from what you have right now and by interpolation from your long term goal’. This helps one realize the importance of identification of long term goal. In my opinion, once a person is convinced about that, it is easy to pull off an interview; more importantly, it is easy to identify which options to prepare for. 
I’d eliminated higher studies at around the middle of fourth year and was convinced to sit for McKinsey and core companies. Resume preparation began at around August with the master resume followed by a resume for core electrical companies which come to campus. Later I made a one page resume for McKinsey. Preparing for McKinsey helped a great deal in preparing for the HR section of the interviews. After McKinsey results, I revised the electrical courses required for the companies which were coming to the campus.
The first day was hectic with a whole lot of companies lined up. One had to be prepared for
all the companies because the shortlist came just the night earlier.

Round: Case Study Interview
Experience: The interview began with a quintessential -“Why don't you tell me something about
yourself?”, The case in round one was about potato chip manufacturing company. Didn't . really end up cracking the case/
Tips: You really need to be calm and only then will the analytical skills and creativity really show. But do not worry - the interviewer shall go out of his/her way to make you feel so.
Just be you and try to establish connecting with the interviewer. A smiling face comes in handy too.
Also, there is a lot of buildup on campus to the start of day zero- just remain calm during that time. It‟s easy to feel over pressurized, especially with all the short-lists coming in, but just relax. It‟s going to be fine.

Round: Case Study Interview
Experience: Case:The client is a large cement company with the highest market share. The second close player is cutting prices. To match the prices the client has also reduced its prices and is facing declining profits. The client has given us 3 weeks to solve the problem.
Structure:
I asked him about the dynamics of the industry. He explained that there is not much difference between the products as well as the cost structures of the company. This meant that even the competitor is losing money by the price war.
I suggested 2 alternatives to solve this: first involved analyzing the cost structure and trying to reduce costs. But the interviewer told me that the client has used all the cost efficiencies possible (this indicates that the interviewer does not want me to go deeper).
Second option that I suggested involved was the Game Theory approach. This involves indicating to the competitor that we will not reduce our prices even if he does so. This I suggested could be done by issuing some way of communication to the competitor. But he said that the competitor is not willing to talk. I could not think of what could be done so he suggested that the client should increase the prices. This will show to the competitor that the client is serious.
Then the interviewer said that after one week, the sales of the client had declined drastically and the competitor had not reduced its prices. This created a problem of inventory.
To solve this data was collected geographically and analyzed. It was found that some dealers had reduced the stocks of the clients cement. The clients did this as they expected the price increase to be temporary and thus wanted to postpone the purchase. I suggested increasing the prices again. This will signal to the dealers that the price increase is not temporary.
Finally he asked me to give some suggestions about the same. I suggested that the dealers should be given discounts based on the average volumes they generate every week and month. This will help in inventory planning. Secondly whenever the price is increased they should be increased all at once and any decrease should be spread over a larger period. This will not allow competitors and dealers to pre-empt the client.
Tips: Even though the ideas might sound outlandish, get them across, they will give you the benefit of thinking out of the box. Try to involve the interviewer in the case as much as possible, if he is interested he will point you out more and more in the right direction.

Round: Case Study Interview
Experience: Started directly with the case. At the end of the case asked me about LBO (Leveraged buyout) and asked me to give an example in the Indian markets .
Case:I was travelling in a taxi when the driver asked me about switching his car and joining the radio cab service such as Meru. What is your advice?
Structure:
I said that we will compare the profits of the two methods and make our decisions based on that. I asked about the revenue and costs of the two and calculated the profit.
I proved that joining the radio cab was better. But the interviewer told me that was the wrong answer. He asked me to go back.
I took the current taxi and approached the different line items one by one. I suggested that if the driver installed an AC he will be able to charge more. But the interviewer asked me to suggest something else.
If the engine of the cab (which was currently diesel) could be replaced by CNG (the radio cab used CNG) the fuel cost reduced drastically making the current cab more profitable. I showed him the calculations.
Tips: Try to be receptive to the hints given by the interviewer in the process. They are extremely important to get to the solution quickly.

General Tips: Do not lose your calm even if you answer wrong.

Round: Case Study Interview
Experience: Very basic scoping questions.1)Re-iterated the question. Confirmed the objective. 2)Asked him if this was attached to a mall. –He said forsimplicity purposes, let us assume it to be a standalone multiplex.
I told him that any multiplex would have mainly four sources of Revenues:1)Ticket Sales 2) Food and Beverages 3) Advertising 4) Parking Fees He askedme to ignore Parking fees and suggest ways to improve revenue for each of the other three categories.I started with Ticket Sales. Ticket Sales = Number of Tickets Sold/Show * Price * Number of shows. 1)Optimize show timings in such a way that more showscan be accommodated. This needs to be considered as a tradeoff to advertising and trailer timings.2)Pricing: Have a dynamic pricing strategy just like in airplanes. You charge each customer different based on the timing of purchase and supply demand equation.

Skill Tips: A very long PI session. Can’t say it was a PI, much like a conversation. The interviewer asked me about my work at Arvind Infrastructure. We discussed about my work for around 5-7 mins. This made me feel very comfortable and I was very much set for my case interview. He was extremely friendly and very good to talk to

Round: Case Study Interview
Experience: Follow the basic Profit –Loss Framework. He asked me to just consider Revenues.Revenues of Retail Company Factors: 1) Number of Footfalls 2) Conversion Rate 3) Products Bought 4) Quantity 5) Price of each product 6) Repeat customers.He asked me to discuss strategies to improve all of the above factors.I don’t remember what I spoke for all factors, but wherever I was unable to think, he was giving me clues. Being from retail background, I was able to relate my experiences with many of the solutions suggested.We talked about availability of products: Asked him to keep safety stock. Forecasting needs to be much better, appropriate information needs to be passed to distributors.Talked aboutplanogram: this is how you display your products, shelf space etc.I discussed with him about the loyalty programs and COD model.The interview was long, but again much like a conversation. Was very much relaxes during the interview and the interviewer was also smiling which made me feel very comfortable
Tips: Knowing your background really helps. One can suggest innovative solutions to the interviewer. BCG was the only consulting shortlist I had and by this time, I was very much determined to get to a closure.

Skill Tips: Tell me about yourself. –When I reached my retail experience part, he said “I am very interested in consumer behavior. Letus do a case on a retail chain.”We also discussed a lot about my retail experience:1)He asked me what were the challenges I faced –I told him inventory management was the biggest problem. Did you use some tools to solve inventory issues?I said yes. Spoke about it for about 2-3 mins.2)Why retail?

Round: Case Study Interview
Experience: Started with the basic Revenues –Costs = profit framework. He asked me to concentrate on revenues. I identified the sources of revenues 1) Consulting 2) Surgeries 3) Lab 4) Pharmacy. He nodded and asked me to move on. I asked him if there was a revenue dip in any of these services to which he replied these are all related and hence the dip is across all services. I asked him about the competition. I asked him whether the competition is offering similar services and how does it charge for its services as compared to the hospital in question. He said “Competition doesn’t specializes in heart surgeries like our hospital. However, it performs all services and their pricing structure is different.I asked him if they were pricing services lower than us to which he replied “no”. He wanted me to think on what could be different in terms of prices. I told him that the structure of pricing is different and hence the hospital may have one fixed fee whereas the competition may have a base fee plus additional charges. The price may come out to be the same but people may perceive it to be cheaper. He appreciated my answer and asked me if I would change the structure of the Hospital in question.I replied that I wouldn’t change the structure. The hospital has a very strong brand and has been following this pricing structure since ages. If it seemingly makes it lower, there is a possibility that patients may come to know about this and its brand may get tarnished. I wasn’t too happy with how I defended but I defended nonetheless.He asked me if I had any questions and I really didn’t have any questions for him. Too tired and nervous to think of anything. However, it is very important to prepare questions for interviewers.
Tips: 1)PI is extremely important. It helps you to develop connect with the interviewer. Also it adds to your confidence. Be genuine about your PI.2)Always keep smiling and be very confident. More than the solution, the interviewer should get good vibes during the interview. Even if you falter, admit that you do not know and you would like to understand from the interview how it needs to be done.3)Be humble.4)Do not ask your colleagues about how their interview experience went. It will just add to your worries and you may end up losing confidence.5)The interview should be more like a conversation.6)Sleep well the night before, do not wait for the schedule. Get up early and check the schedule. Do one case which you are most confident about the day of the interview.7)Again keep smiling.
