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. They asked both technical questions (based on the project I talked about with them) and behavioral questions (e.g., "Have you ever had difficulty working with someone in a team?").

They flew me to Dallas for the third round. Two managers each interviewed me for one hour. Both were heavily technical interview sessions.

I was not happy with that. Although I was interviewing for a digital verification role, the first manager grilled me hard on analog circuit and device physics related questions.
