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.

The interview process was smooth, and my interviewer was nice. About 6 or 7 technical questions and 5 behavioral asked. Technical questions were all on op-amps and the behavioral were mostly centered around how I dealt with challenges and maybe 2 on my projects that I had on my resume.
