Three phone interviews. One on-site. They paid for flight and hotel. ~5 hour interview with 6 people (3 groups of 2). Overall, a fairly painless experience. Amazon was far more taxing. If your going to interview, don't be stressed; it won't be difficult.

I was contacted by a recruiter within 9 hours of applying with my resume. Ended up taking four interviews total.[5 weeks] So if you are browsing here like I was mid-process, HAVE HOPE! Interviews will differ from position to position so make sure and focus on your core-area. They will drill your arsehole in the area which you are applying for(..expectedly) so prep as if it were an exam. However, do not script answers like a door-knob. Nobody likes that.
