A recruiter contacted me, to talk about the potential fit over the phone, then went through a coding questionnaire. After that, 2 more phone interviews with short coding exercises. So far so good, then I was asked to come onsite for an interview, 15-20 minute presentation followed by 6 one on one interviews with senior engineers. Electronics, coding, and general firmware design questions. One became aggressive and condescending about one of my projects, and I was as professional about it as I could be. He was arrogant and close minded with a horrible attitude, even though I really knew what I was talking about. The other 5 engineers were very enjoyable and the overall experience was good, however they said they would move forward with another candidate.
