In person, one hour broken up into two 30 minute interviews. First half was with the engineering manager and went over the basics, your resume, what they do, what you'll do, then some generic hypothetical situation. Second half was with other test engineers which went over your resume again and more technical questions. Manager was fairly rude, very rushed and wanted to end his section fast. I could tell he really didn't like something on my resume leading me to question why this interview was even scheduled in the first place if there was a dealbreaker right on my resume, wasting both of our times. The test engineers seemed like great people though.

Was reached out directly for the role by HR. Phone interview then in person in a conference room. First part was with HR and just went over my background. Second part was with the hiring manager where he asked a couple questions, some of which would require real in depth knowledge on the chips they make (outside of any curriculum i know of and they knew i was a recent grad). he then explained there would be long hours with only promises of "we are working to make it better within 9 months." Was texted the next day i was no longer being considered

Went through HR first, seemed to be a bit of a hurdle to go through. Once talked to actual engineers it was a great interview process. Asked mixture of technical questions, as well as general intelligence questions, and personality/social questions.
