Round: Test
Experience: Written test (Cut off: 7): The test consisted of 2 sectionsPart A (60 min): MCQ's with negatives on general aptitude, permutation & combination (P&C) and Probability.Part B (40 min): This was a subjective section. One or two problems on probability/P&C and few problems on data structures and algorithms (we were asked to write code).
Duration: 60+40 minutes

Round: Other Interview
Experience: 22 candidates were selected for interview which consisted of 2 or 3 rounds. First round: They asked me to explain my summer project. In the Second round, a few problems on P&C/Probability and couple of questions on DSA. Final round: An open problem. For example: estimate the population of Mangalore.

General Tips: If you don't know an answer, tell the interviewer the same. Lying would do more harm than good because they definitely know more than us and will find out very easily. It was Challenging and a great learning experience They test your fundamentals and don't ask too many difficult questions.
Skill Tips: If they ask you to explain what you did in your summer internship, explain it in as simple a language as possible so that even a person with no background in the subject will be able to understand it. Don't use complicated terms because they are looking for people who can express themselves well. Prepare for aptitude sincerely. You might neglect it thinking "It's just apti, what can they ask?". The problem will arise when you know how to solve the question but it might take a really long time to work it out. Practice makes a man perfect. For algorithms, code every question you have tried to solve. Interviewers look for people who can write efficient and readable code. ["Use proper names for variables"]. When they ask you a question, they don't expect you to arrive at the exact solution. They look for the structure in your solution i.e have you considered the necessary parameters and does there exist a logical progression from one step to the next. If you are asked an open problem, don't panic. Keep asking questions to get a proper understanding of the problem and try to give them multiple solutions and reason out why each solution might be right or wrong.

Round: Group Discussion
Experience: It was a topic I had no clue about. I was sandwiched by two people who for some reason seemed like research scholars on that topic. I was quiet throughout most of the discussion.
