4 rounds of interviews with the team manager, lead, and the rest of the team. totally 3.5 hours interview plus 30 minutes of my presentation. very detailed technical questions and a few personality questions.

I applied through LinkedIn. They emailed me and asked for a MS team meeting for 45 minutes with team leader and hiring manager. They did not ask any personal questions. They introduce themselves and ask me to introduce myself. Then ask about the gap in my resume. After that start technical questions. The hiring manager kept asking about three bullet points in one of my recent job. I explained many times but he laughed and it seem to me he thought something else (but I was very clear. I had interview with SpaceX and Apple and they understood what I meant). I found it weird. The team leader asked technical questions about vibration. I have done both CFD and FEA simulation. It seems like they wanted someone to know the both. They asked me which one I prefer and I said if I wanted to rank I would say Structural analysis first and then CFD. Then he kinda get disappointed and explained to me that we need some one with both knowledge (which I have).
