Placed 5 candidates with 2 interviewers. We were supposed to discuss random topics (is TV damaging society?). The interviewers intervened and asked contradictory questions. If they saw you were unsure about your answer, they pressed more so brace yourself. However, the interviewers were very friendly. Articulate clearly your point of view.

First round with HR. Second round is a group discussion. Given a topic, there is no right or wrong. I think they are trying to understand your thinking process and how you deal with problems.
