There were 3 interviews. First two were somewhat technical, with questions related to coding languages, points from resume, and previous experiences. Small algorithms section that was pretty simple. Final interview for fit I assume. Asked about time at school, thoughts on emerging technologies, previous experience, etc.

Interview Process was tough, but the interviewer will definitely make you comfortable during the interview process. I got the same felling in all the 4 rounds of interview. The questions are thought provoking. Overall it's a very good experience.
