first, they take an aptitude test, then 2 technical rounds with 1 HR round.They asked me questions about the projects I've done. They also asked me about the bond of 2 years which I refused and there was a coding round which I survived but the aptitude part seems to be difficult for me as i didn't able to solve some of the questions. If you've done a preparation for CAT then it'll be easy for you. I didn't do that which I regret.
