I got to know about it's off-campus drive through a job portal. It was just 1 day before that I got to know. I din't prepare anything and I had to travel for around 6 hours to reach the venue. I couldn't revise properly. First Round was online-written test. It had 3-sections: Aptitude, Reasoning & computer knowledge. The standard of the questions was very high. I just loved solving the aptitude problems. Reasoning was also very good. In Computer section, mostly theory questions were asked. Some of them were debugging, spotting errors in a given program etc. Out of around 500-600 members, 47 got selected & I was one among them. Second Round- It's the technical round. If you're not asked to leave for day, you can expect to be called for next round. Only one program was asked, and rest, i felt they checked how you work under stress, how you work in a team, behavior with your boss etc. You just need to be confident enough. Third Round- It's the HR round. He asked me what were you asked in the technical round & I told him. Then he gave me 1 program to write & 3 puzzles to solve. He left the room & I tried solving them. By the time he was back, I couldn't solve one of them. They just see what methods you apply to solve them.
