There were 2 interviews. First interview was a 1:1 in my school. I was asked about my classes and had to code on a whiteboard. Interviewer was friendly and answered all my questions. Second interview was a phone screen. Had to write code in C and was asked bit manipulation questions, optimization and multi-threading questions. Interviewer was again very pleasant. I also attended an info session in between my two interviews where the recruiter talked about Dolby. I won some movie vouchers there by answering Dolby trivia questions :)
