It was a walk-in interview. Around 500 people turned up. The first round was an aptitude test. 25 Easy questions. After that we had a sort of interview which was technical and HR combination. Then we were asked to leave for the day. A week after that, we received a mail informing us about the shortlisting. The next round was technical interview. I got rejected here. One of my friend cleared it and went to HR round. He is, at the time of writing awaiting results. He said there are 2 more rounds: interviews by Vice president and President.
