BCG Intern Interview Questions, Process, and Tips

Round: Case Study Interview
Experience: The first round required a systematic approach and therefore adequate preparation helped to solve this case in a structured manner.
Tips: Overall presenting ideas with logic and structure helped me.

Round: Case Study Interview
Experience: The second round did not go well for me. Here it was easy to get lost in the many levels of the case and therefore it would be useful to attempt some quantitative cases as well. Along with this, it was important to stay calm when solving the case was hard which I was not able to do well enough.

General Tips: Prepare hard and work on exploring all possible options within a case.

Round: Case Study Interview
Experience: If I am an authorized service centre for a mobile company and I want to set up my own mobile service centre to service handsets of products whose warranties have expired, how should I enter the market.
He wasn’t convinced with my why consult answer and coz of that I screwed up my case too. Also, it was the 1st interview for the day and screwed up coz of nervousness. Didn’t ask qualifying questions. Structure was all over the place.

Round: Case Study Interview
Experience: Qualifying questions were perfect. Applied the correct approach. Detected the problem in the after sales service. Perfect recommendations.

Round: Case Study Interview
Experience: Discussed about the various possibilities of the revenues decline –any particular geography, product or channel. There was a particular region where the sales were declining. The sales in the region primarily consisted of 2 tractor models – 35 and 45 hp.
Tried to approach the problem by dividing the issue areas between Internal and External.
Internal – Company related issues related to 4Ps. External – Competition, Consumer Behaving Pattern or External Environment overall (PESTLE).
The prices of the product w.r.t to competitors was at par. However, the maintenance costs was higher as compared to competitors and hence the sales were going down.

Solution:
Proposed a solution of providing extended warranty. Also the excess costs incurred by the company could be recovered by increasing costs of the other 2 tractors (as its market price was slightly lower than its competitors) compromise on the profits.

General Tips: Just be comprehensive. It does no matter if reach the solution or not. Just be exhaustive and have a structured approach.

Round: Case Study Interview
Experience: Two things in the problem statement set the path for me.
a. “Phase -1 trials”, so phase -2, so phase-3 etc had to be looked into – basically the whole development stage from a drug in a lab to a drug in the marketplace.
b. “for what amount” – clearly this case demanded working with numbers, because it was not just a yes/no question, but also asked an approximate deal price.

Solving the case.
a) I laid out the value chain in development of a drug.
b) The interviewer on prodding gave me costs involved in the phased clinical trials and their probabilities of success.
c) CATCH: Phase 3 trials success of failures probability does not affect the overall outcome in expenditure, as even if it is a failure, you have spent the money
d) So I have an approximate numbers on cost in different scenarios.
e) Now, I tried to estimate the potential revenue that can be earned from this drug. The interviewer gave the selling price of the drug has been fixed at USD1000. So now its more of a question of market sizing.
f) Since the company is a global pharma giant, it would be selling all over the world.
g) The problem was now reduced to finding the number of potential male bald customers worldwide ready to shell out USD1000 for a cure.
h) The math worked out that there was no way to make money from this drug (It took a little bit of guts to state this conclusion to the interviewer), and the company abandon this project. Or better still, if somebody is ready to buy the right, just sell it for any amount above the costs you have incurred so far.

Round: Case Study Interview
Experience: First I tried to understand the Nigerian motorcycle market. Also, I tried to understand if there was any possibility of the Indian maker to sell cheap – that possibility was ruled out. So, if cost leadership does not work, product differentiation will. How could we then differentiate our product?

a) CATCH: As it turned out in the course of our discussion, the motorcycles were used as taxis
b) The drivers owned the motorcycles and plied pillions around the city for a fee.
c) I worked out the math for these chinese motorcycles -buying cost, maintenance, life, mileage, etc.
d) If the Indian client could beat that number, we could have a winner - the buying cost was high, but we were better on mileage, on life (3 years vs 2 years for the chinese product) and on maintenance. Still the number was not favourable.
e) Next came the idea, that if we could not reduce the cost for the drivers, can we improve the revenue. An idea that I blurted out, but which turned out to be the one the interviewer was looking for – was to have a longer seat so that a total of three people could ride the motorcycle comfortably.
f) Now the numbers started making sense. Also note that the previous numbers would have changed, because the mileage with 3 people on board will be less than 2 ppl onboard. Also, the amount individual customers are ready to shell out for a shared taxi will be lesser than for a private taxi. All these changes accounted for, the numbers still looked positive.
g) So a go ahead was declared.
h) Now came the second part, given that we decide to enter Nigeria – how do we position ourselves as a brand and convince the locals to tru out our new expensive product –the benefits of which can only be ascertained after a period of one or two years i) The answer came in renting out these bikes to the drivers on a trial basis, and let them appreciate our better bikes and let word of mouth do the rest.

General Tips: a). Be calm, but be enthusiastic in the interview. Enthusiasm shows.
b). Make the interview a two way process. Let the interviewer help you solve the problem. He will drop hints. LISTEN to them.

Round: Case Study Interview
Experience: Identified that the problem could either be surplus or wastage. Understood the inventory procurement and management system. Took a sample fruit for a given week and proceeded with inventory optimization. Developed alternative inventory plans and selected the best one. Then asked to synthesize.

Round: Case Study Interview
Experience: The interviewer didn’t have my CV. He preferred a brief introduction. Probed about other shortlists and interviews I had.
Then opened an elaborate PPT and walked me through the slides. It was a Dairy Farming Corp. based out of western Europe and we looked at acquisition targets across 4 markets. After 10 minutes of running me through a number of tables and graphs, I was given a minute to think and recommend the best option for the client. I Didn’t lose sight of the bigger picture. Concluded with a recommendation and case synthesis.

General Tips: 1. Respond to the tone of the interviewer.
2. Being composed matters.

Round: Case Study Interview
Experience: Had to talk about working capital requirement through dealer terms, inventory requirement, etc.

Round: Case Study Interview
Experience: Two parts 1) draw the decision tree about how would you look at a niche building materials business and 2) come up with a formula with clear variables to estimate the overall market size

Round: Guesstimate Interview
Experience: Straightforward guesstimate with important cuts being, % of people that consume tomatoes, type of people that will buy from such a store vs regular vegetable vendor, etc
Tips: They were not looking for exhaustively looking and covering all points, instead wanted you to reach solution immediately and then completely cover them.

General Tips: While solving cases we emphasize a lot on MECE thinking, trying to cover everything before reaching a solution. While that is important to make sure we don’t miss out on any point, on the day of interview it’s different with just 15-20 mins per interview. Try practising in such time frame closer the case within least time possible.

Round: Case Study Interview
Experience: I first found out the demand and competition in Nigeria. Also looked at the company’s capacity to meet the price requirements of the customer. Important point was that the twowheelers were used as taxi in Nigeria. This point came out when I got an answer to the amount of usage of the product as 50,000 kms annually which was very high. Price we could offer was higher than competition so I suggested changing the design to have two customers per ride than just one, there by increasing revenue per ride and thus customer’s willingness to pay higher.
Then interviewer asked questions about how to market it. I suggested a few advertising ideas like showing increase in standard of living of taxi driver due to usage of product.
Then question was how to get over the inertia that people felt in buying as no one had used our product. For this my options ranged from approaching taxi driver unions to limited number of product units in market for a free 6 month period for the user to experience the product. I also suggested a more spread out distribution within the country to increase visibility of product
Tips: The first round allowed me to look at a diverse set of options across functions such as marketing, pricing, design, etc. The good point was identifying early in the interview that the two-wheeler
was used as a taxi. Another good thing was that with each question that the interviewer put forward to reject my suggestion, I was able to give another alternative option

Round: Case Study Interview
Experience: I studied the value chain and understood how product complains were generated and solution provided by company. In this I found that the dealer’s engineer was responsible for checking
validity of complains and it was the dealer who got a commission for every complaint that he managed or solved. This was major point that hinted at possible collusion between customer and dealer. On further probing it was found that there was a fraud happening at the dealer’s end. The dealer was generating false complains to earn more commission. To solve the issue I suggested having a company engineer look into the complaint validity. I also suggested having a remote way of monitoring the product health.
Both these solutions were a bit time taking and costly. So a better solution from me was to monitor each product and number of complains it generated in a given period of time. If the same product generates more than normal number of complains in a period, it can hint at possible collusion and the firm can look into that complain before authorizing the warranty.
Tips: Second round was more about finding the issue rather than ideation. I was able to unearth the issue well and solution suggested was very practical according to the interviewer.


Round: Case Study Interview
Experience: I looked at regions where the selling price of product was high and suggested we target these regions. Looked at various costs to the dealer or seller of the cement such as inventory storage costs, etc and how we can give him incentive to store and sell our product. Basically it was about increasing the ROI of the dealer wrt costs he incurs to keep our product and benefits he receives by selling it.
Tips: Third round was more about gelling with the Partner and being calm. At times when he probed me, I was able to maintain composure.

General Tips: It is always good to be prepared with your HR answers. That is not to suggest that you cram them up. They need to be genuine and your preparation should involve having a few pointers for each answer.
Most important thing is staying calm and composed and to enjoy the process. You should come across as someone who is enthusiastic about solving problems. Isolate each interview and don’t let it affect next interviews.
It is good to have frameworks at the back of your mind for each type of case. But in the interview, try to ask good qualifying question before putting a framework on paper.
Think aloud and let the interviewer be involved with you in the process of reaching a solution.
