There were 3 rounds of interview although no filtering was done after any round. These were Technical Round, HR Round, Managerial Round. Before this an aptitude test was conducted to filter students. It consisted of Logical ability and Verbal Ability(email writing). I was exempted from the logical ability test on the basis of Academic Criteria set by TCS. On the first day was Pre-Placement talk followed by Aptitude test on 2nd day and finally interviews on 3rd day. I cleared the verbal ability and sat for the interviews. Thankfully, I cleared all and got an offer from TCS the day after the interviews!! Out of 300 students who applied, 200 were shortlisted for the Interviews. The process was quite confusing as students were asked to leave after 1-2 rounds without any indication whether they had been rejected or not. Prepare well for the aptitude as it was quite tough according to what my friends told me. Practice probability thoroughly.
