I had two phone interviews.

Each interview was one hour and 0.5 hour long and consisted of basic C programming questions, including bit manipulation and standard C concepts. The C++ portion was in detail, with in-depth questions on STL libraries, data structures, and linked lists.

After a week, the HR called me to set up the onsite interview. This was a long process with a series of interviewers. Each tested my skills on programming, video codec knowledge, compiler optimization, and basic OS concepts.

I did fairly well but received a rejection after another week.
