Phone screen, onsite and follow up phone interview. I was interviewing for a systems role, so the questions I was asked were mostly system oriented (what's the tradeoff between design x and y for application b), with a few medium difficulty coding questions thrown in there. They also wanted to make sure I had domain specific knowledge, so it's very helpful to know a lot about what the team you're interviewing for does.

The initial phone screens were to gauge my interests (1 Hr and 2 Technical Phone Screen) and then I was recommended to a team which interviewed me. There were 4 technical rounds onsite.
