I have attend a walkin interview. There were only 3 rounds. First one was written exam. I cleared that and was asked to come for other 2 rounds after 3 weeks. 2 nd round was supervisory round and the 3rd was manager round.

They stress both on subject and behavioural questns as well. If u have done internship or worked on any project, questns r asked 4m part. Have a good grip on subject comprehensively, with knowledge on markets and recent events.
