Three rounds. The first round was on campus. The manager asked about my project (I could talk about any project). It was more behavioral. The second round was a web-session interview. Two engineers asked about my projects, and asked both technical (they asked me questions based on the project I talked with them) and behavioral questions (have you ever had difficulty working with someone in a team?). They flew me in Dallas for the third round. Two managers each asked me for one hour. Both were heavily technical interview sessions.
I was not happy in that although I was in for a digital verification role, the first manager grilled me hard on analog circuit and device physics related questions.
