Tesla Senior Electrical Engineer interview questions

I applied online and then got contacted by email about 3 weeks after. I got an initial interview by an HR person and then another interview by phone by the hiring manager. After talking with him on the phone he asked me to go for an on site interview. The interview happened about 3 weeks after our phone interview. I was asked to do a technical presentation and then I interview with each member of the team for about 30 to 45 mins.
