Technical Aptitude Test followed by Personal Technical Interview. Interview takes a day only as so many candidates comes from different states. HR will inform you whether you are selected or not via mail. Do mention in the CV what you know only, as they'll ask you each and everything what you have mentioned in your CV (I don't need to tell you how much knowledge they have of their area). Panel will be having minimum 3 Professors from your area. So it's better to mention only those things which you know completely.

First, it was a written exam on probability and statistics, followed by an interview. One Python programming question to write pseudo code and logic. Process was of one whole day and interview was offline
