Round: Case Study Interview
Experience: One mini calculative case interview and 2 major calculative
General Tips: Don’t relax too much and do prepare religiously inspite of whether or not your wingie or close friend is taking placements seriously. Also, do help out your wing mates once you are done with yours. There is no better joy than seeing a close friend landing up a dream job. Most importantly, never lose hope. This comes from a 7.1 who failed to make into the shortlists of every company for internships and still landed a job within the first 3 hours on the first day. Just keep believing you’ll do well and you would.

Interview Preparation Tips
Experience: After the 4th round, they told me that they were making me an offer, and that was a big moment of relief for me.
General Tips: Prepare well for the GDs’ and interview because, a good CV only takes you to the interview and becomes irrelevant after that. Only preparation matters in selection. Also, prioritize your sectors based on your interest, and profile. Be realistic and practical while doing this. Also, If possible, keep one or two options ready beforehand (Ph.D., MBA, civil services, startup/family business) in case you are not able to crack a good job as it prevents you from getting panic. Also, if you are shortlisted in multiple companies in a single slot, do take a friend with you to manage everything. Never be overconfident if you have a very good CV. There have been various instances where many so-called high profile people have struggled with placements due to lack of preparation. Also, do not waste your time preparing for all the sectors, as you won’t be able to become a master in any of them.

Interview Questionnaire
2 Questions
- Q1. Simple Case Interview
- Q2. Main case Round
Interview Preparation Tips
Experience: Adaptive DI test. Level of difficulty less than CAT.
Round: Case Study Interview
Experience: This is a very simple case interview. The case was as follows: Client is a micro-lender, they loan funds from a big bank @ 6% SI and loan out the money to farmers at 10% and 20% SI. The segmentation is 60% and 40% respectively. Calculate profit/customer. What is the profit if 2% customers default (uniformly from both segments) on the loan? (Ans: loss incurred)
Tips: This is a very simple round, just stick to the essentials of keeping your structure + calculations neat & clean. Communicate well. You'll get through.
Round: Case Study Interview
Experience: Case: We are a telecom company, planning to launch a new subscription plan. Decide if we should go ahead or not. The plan is as follows: We charge the customers $0.99 for the first 20 minutes and $0.08/minute thereafter. The cost incurred by the company is $0.07/minute. Should we go ahead with the plan?
You will be asked to draw a graph between Profit and minutes spent on a call. To come to a decision you might ask the interviewer for some more data like the distribution or the average time spent by a customer on a call. But none of this is information can be used to decide if we should go ahead with the plan. Unless you have a distribution of percentage of customers vs time spent on an avg call, you can not decide the fate of the plan.
On our campus, almost everybody answered a yes(go ahead) or a no for the plan and still got rejected. I think the actual answer is "None of the above. With the present information nobody can predict if the plan will be profitable in the long run.
Please do not say we can use historical data to come to a conclusion, I did, the question he then posed to me is can we really use historical data to predict the usage pattern of this plan by our customers?? The answer is no, we can not use historical data, as the customers will have an incentive to speak for close to 20 minutes per call.
I also looked at the problem from a customers point of view to check if a customer has an incentive to pick this plan over the others. I asked for the cheapest plan/s out in the market currently, so the interviewer told me that the cheapest plan cost the customer $0.08/minute.
After getting this data, I looked at intersection of the time band at which it becomes cheaper for the customer to pick our plan over the 8 cents plan and the time band which is profitable for us.
I came to the conclusion that the band is very narrow to be profitable and that I do not think that it will generate net profits. So we should not go ahead with the plan.
I assumed that there wont be a large chunk of customers in the above mentioned time band. This is what I think my mistake was.
I believe there is no way of definitely saying whether we should go ahead or not. Hence the answer must be Cant be Determined.
FYI: I also suggested him to launch it in a small region/zone so as to figure out the distribution of customers. No good.
