Tesla interview questions

This interview consisted of 4 interviews. This was for an internship position. Ultimately, I had to take the initiative to follow up and see if they had made their decision. The follow-up was not there, and I do think I would have had the dreaded "ghosting" if I had not been proactive myself. All for an internship that I ultimately did not get.

Meeting with recruiter, short technical session with hiring manager. Hiring manager asked for a high level overview of why Tesla battery cooling designed changed between two models year over year.
