Tesla Mechanical Design Engineer interview questions

Had a technical exam, twelve questions, for one and a half hours. Each question was to do with a different topic to see your experience with each topic. It was multiple choice but you must scan and submit your working

Had 3 rounds of virtual 45 minute technical interviews followed by a presentation to the team and 6 additional technical interviews. Only one person asked a couple of questions about my experience or behavioral question. Everyone was generally nice but focused on first principles and didn't really care what I had done.
