Met a recruiter at a campus career fair and was invited to an interview the following morning. The interview lasted about 45 minutes and consisted primarily of technical questions ranging from transistors to C programming. A week later, I was invited to come onsite for 2nd round interviews. The interviews lasted all morning and consisted of 4 40-minute interviews consecutively, all of which were technical. The interviews were followed by lunch with the interviewers and then a tour of the testing facilities.

I got an email from the hiring manager saying they needed to talk more and ask me questions, we set-up a date and time, the interview duration was 30 mins, so I thought it would be an introductury interview. it wasn't, it was a full interview that the hiring manager and another senior engineer attended. we all introduced ourselves and what we do, and then the technical questions began but there was barely any time left. so the interview was concluded,
