Had to undergo 7 rounds in the interview. Intro, aptitude, test to test your listening skills, voice and ascent, grammar, Technical, ops and HR. You will talk only in 1st and last 2 rounds. Most of the candidates will be rejected in 1 st round itself. There were 33 people with in 1 st round and only 2 got selected but the other guy got out in voice and ascent.

I applied through college or university. The process took one day. The overall process was having 5 rounds and each round took 30 minutes. The first round was Jam session. The second round was online test,the test contains technical,logical and english part. If you clear this round you will be facing four interviews-communication,technical,operational and hr. The technical questions were very basic.
