4 rounds: aptitude Technical,mangement and Human resources aptitude: basic stuff, can use standard books and 20-30 days to master the questions. Technical: well, it depends on the panel.To be honest,my experience was quite horrible, and therefore I wasn't able to advance. Even after my Technical round was over by 12:00pm, I wasn't informed whether I had cleared the round.Even till 8:00 pm at night, it wasn't clear whether I had cleared the round. Total Chaos,no transparency.
