Three interviews in total , the first one was a campus interview and then a week later i got a webcam interview. Both interviews were behavioral and technical, very basic technical questions though such as low pass filter and op amps. The behavioral questions are tougher since they need specific examples of the answers they are looking for. The third interview was a presentation and they flew me out to dallas. They did not ask anything about my project presentation, other than that they were great people and it was worth the experience.

3 rounds. The first was behavioral with very simple technical questions -- what's the offset voltage of an ideal op am, setup & hold time, etc. Second was mostly behavioral Third was behavioral with focus on my resume.
