Process consists of 5 rounds. Cleared all of them except the last round only to be asked questions on topics which I had already mentioned I had not worked on. Interviewers do it for the sake of formality. Even if you answered correctly in the previous rounds, it won't matter if they have already decided on rejecting you by saying that your skills don't fit our requirements. My advice- Please scan and shortlist resume carefully, so that you know what is to be expected from a candidate and if they fit your requirements or not. Please don't waste time and energy by taking so many rounds. Reject in the initial phase if that's what you are planning to do. PS- HR representatives were very nice and friendly. They ensured a smooth process.
