Well, there were four rounds, and there was mass elimination in every round. the first round was quite easy. They check your English vocab and grammar, and followed by the Watson glacer test which is basically about conclusions and assumptions, that was quite hard and the third round was the versant test, where a pre recorded voice of different people will be played in American accent, and we Will have to repeat, reconstruct and summarize it. The last was a interview through phone or face to face, where they need you to speak and relate to the questions they ask and few scenarios. If you're good enough to convince them with proper conclusions, then the chances of getting shortlisted is highly likely.
