It was a 30-minute on-campus interview. Straight to technical questions. Very nice interviewer; he did not give as much guidance as I thought he would. Very straightforward setup, and questions moved from high-level to full-on coding.

The interview process involved several stages: * A recruiter interview. * Two phone interviews with the hiring manager and a developer. * An onsite interview with five rounds. This process took about three weeks. Everyone was very professiona

It was difficult. There were many data structure and algorithm questions. To be fair, I should have prepared for at least another week, but I wasn't given enough time. Also, there were a lot of questions about threading.
