three rounds all technical. Mainly basic and theory questions at first but in later interviews the also asked me about my past projects. Beware of trick questions and know your fundamentals well. they were nice people though.

Interview was very straightforward. A couple minutes expanding on details about your resume (projects, knowledge, experience using certain software tools, etc). Bulk of the interview was a circuits technical question, going into transistors, op amps, microelectronics, etc.
