Tesla Mechanical Design Engineer interview questions

Was reached out to to take an aptitude test online and given a few days to study (given the list of topics). Once I had passed the aptitude test, I did a preliminary interview with the head of the division I would be working under. After this interview, I did a more technical interview with an engineer on the team. I then did another technical interview with an engineer on a different team. Had I "passed" these interviews I would have had to do a presentation for a panel of engineers, but I didn't hear anything back/get any follow-up after the third interview. Overall, everyone was very friendly, very informative, and seemed very willing to make the process comfortable and smooth (up to not hearing back anyway).
