Interview Preparation Tips

Round: Test
Experience: The first round was an online test with maths, logic and english questions. If you have prepared for any of the standardised tests (GMAT, GRE, CAT etc.), the test would be pretty simple. And try to answer as many questions as possible.
Tips: It would be really helpful if you give atleast your first attempt to any of the exams like GMAT, GRE etc. This is only for the online test because the pattern is quite similar to GMAT. For the interviews, be prepared for a set of standard questions asked during interviews that you can easily find online.

General Tips: Be prepared to spend all day at the interviews. You might not even get a lunch break. Sometimes the interview calls are late at night and also extend upto 2-3am. Be alert during the Pre-placement talk because the interviewers ask you questions from that too. I would advice you to ask questions to the interviewer when asked to regarding the company.
Don't write fake stuff in resume. At max you can exaggerate a bit in your CV. The panel does question you on your CV. Everything in it must be justified.
