For my first interview at Tesla, it was a phone screening interview with the recruiting manager, and we went over some of my background and work experiences based on my resume for 15 minutes. He asked me about what makes me interested in Tesla at the end of our conversation. Then, he arranged the on-site interview for my second interview. I had 5 interviewers (some were designers and engineers). I had 1:1 interviews with 5 different people for every 30 minutes and generally asked me questions about what I did for my career and what I can do for the position. Third interview was with the team lead through the phone screening.
