Interviews: + HR/behavioral phone (recruiter) + Technical phone (hiring manager) + On-site (6 separate interviews) The on-site interview started highly technical, then software block diagrams, project manager discussion, lunch interview with 3 managers, Arduino coding project, finished with a discussion about one of my projects. Make sure you can talk in-depth about your projects at internships, side projects, etc. Also, prepare questions in advance (of course). And practice the general questions (have stories to illustrate behavioral questions). Overall, the overall experience was quite good. Everyone was responsive, very interested in the work they do and the mission of the company. I usually heard back within a week after each interview, sometimes a just couple days. Ultimately turned down the offer because I received a more interesting offer.

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.
