one skype interview with an engineer, asked questions about your resume and then a technical question, then another skype interview, same thing, if you passed that one, then you fly to CA for onsite interviews

The recruiter gives a short self-introduction, then give two algorithm questions, the recruiter give some hints if you have no idea how to solve the problem, I didn't give the best solution for the first one, then recruiter move on to next one, I solve the next one.
