Interview Preparation Tips
Experience: It was basic data interpretation questions. They gave us a graph or a couple of graphs and asked questions based on them. Calculators were permitted, so it was mostly about speed and application.
Tips: Solve CAT level questions for Data Interpretation, which is a more advanced level. That should make these questions relatively easy. Just practice sums as much as possible to crack this first round.
Duration: 35 minutes
Total Questions: 30
Round: Case Study Interview
Experience: The company basically looks for how logically you think as well as how effectively you can communicate while working on a problem. The question will be a relatively straightforward case with basic math involved. There are three rounds of Case Interviews, with varying problem statements, to test your thought and working process
Tips: Ensure you write everything systematically, and keep the conversation going with your interviewer. Tell him/her what you are doing constantly. Double check your work, ask questions and be calm and confident. The process is very relaxed so take your time. If you have a doubt, don't hesitate to get it clarified. Organise your workings clearly so you may come back to it easily. Don't get flustered if you make a mistake, check your working and correct it.
Round: Behavioural Interview
Experience: This was the last round of interviews. It was very relaxed. If you've made it this far then you have a very good chance of receiving an offer letter. It's more of an HR Interview with easy flowing conversation. It is to gauge your communication ability and to get a better understanding of what you've done previousy in terms of work, projects, etc.
Tips: Be calm. It's a very relaxed interview with a flowing conversation. Be confident. Don't be afraid to take a moment to think. Ensure you answer the questions in a manner that highlights previous work that you've done, or any other accomplishments. DON'T LIE. Be genuine and calm.
General Tips: I've already said all there is to say earlier. But I'll re-iterate. The interviewers are very nice and relaxed. So just be yourself. Communicate effectively and be organised in your thoughts and workings.
Skill Tips: Don't be nervous. The process is well organised and conducted. It is swift and interesting too. Just stay calm and don't be shy.

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.

They have an office in India just to show the Investors that they plan on expanding and are investing in India and Philippines. I don't think the real work happens here.

Interview Preparation Tips
Experience: The test basically involved solving 15 Data interpretation questions. The test was pretty easy, and hence accuracy was very important to qualify for the next round.

Total Questions: 15
Round: Case Study Interview
Experience: Initially the interviewer tests your basically conceptual knowledge regarding the cost and revenue streams for a loan and then expects you to calculate the average profit given the required data. This was a pretty small interview lasting only about 10-12 minutes or so.
Tips: Keep conversing with the interviewer and clarify any doubts. Do not mess up with the calculation.
Round: Case Study Interview
Experience: Again, the interviewer tests your basic understanding regarding making a decision to select between two marketing schemes. Then, after being provided relevant information, you are expected to make an informed decision, do the break-even analysis and plot a graph.
Tips: You need to show the interviewer your grasp of business concepts. A good knowledge about economics and a business acumen helps. The math is easy, just be careful not to mess it up. Also, keep conversing with the interviewer and help him understand your line of thinking, this would enable him to assist you and get you on the right path.

Tips: Again, think aloud and use your common sense if ever you feel that you do not know an answer. But mainly be confident.
Round: Behavioural Interview
Experience: The interviewer is very friendly and it is more of a chat than an interview. Also, they will get into the specifics of the example you provide just to understand the situation better and to know how you handled the situation.
Tips: Be well prepared with all the general HR and behavioral questions and think about specific examples that you would like to bring up.
General Tips: To sum it up, more than anything, just be confident.
Skill Tips: If you are selected for the interview, chances are that you already have the necessary math skills to succeed. Remember, the only things which are going to get you through are confidence, alertness and business acumen.
