Three rounds. First round was Aptitude + Programming Concepts. Some questions were writing the output of the given code. Time is not a constraint, they give enough time to complete the test (I think it was 90 minutes for 9 questions). Second round was coding. 3 hours, 2 questions. The point here is again time is not a constraint. If you get the logic, you can finish the round within the given time. One question was quite easy, the other was of higher standard. I passed around 19/28 test cases. 11 of us were shortlisted for Personal Interview, which was the third round. In the interview, I was first asked how I could improve the codes to better my result. The interviewer was somewhat convinced. The next question, I could not answer completely. My answer used too much memory, and they wanted an answer which didn't use extra memory. The interview was very detailed, around 1 hour. The one person who was offered Full-time position had passed 28/28 test cases in the coding round. I think there was an additional HR round for him. There were two internship positions offered. I did not get in.
