Previously had a recommendation from a former intern to check the company out at one of their on-campus events, and specifically who to talk to. At the event, I spoke with a rep and we talked about some past work specific to hardware design. The first technical interview was scheduled the next day. It involved some more in depth conversation about relevant work and working through some simple electronic circuits - op amp, MOSFETs, diodes, filters...wasn't 100% on everything but the idea was to demonstrate the problem solving process. On site interview was 2 weeks later. After an HR interview, I spoke with some managers where we did a similar interview as before, including some more circuit worksheets. Afterwards, there was a campus tour.

The phone screen was pretty chill. They asked a lot about my resume and past work/internship experiences. It was mostly very behavioral, only a few questions were asked about basic technical understanding.
