Had an on-campus interview after submitting my resume. About a month later I got an e-mail inviting my for an on-site interview. It consisted of two interviews, a tour, and lunch. Got a call 3-4 days later with an offer.
Interview questions were mostly about my background. In the on campus round they asked a few questions about the c++ API, and threading, at a basic level. The on-site interviews had some behavioral questions mixed.
