I went through 3 rounds of interview. Every round was a selection round. This interview happened a year back, so I'll write whatever I remember. Round 1: HR Interview - Things based on your CV, interest, job. - to test your communication skills - for some people the first round itself was a stress interview, however I feel that one allows the interviewer to create that stress on you. If you're relaxed and smiling, nothing can stop you from getting shortlisted - they also try to judge if you're flexible enough to fit in the company culture - to talk about it, the culture is quite informal and they would be looking out for people who are beyond academics with good general awareness.
