Tesla Intern interview questions

Asked what is your biggest technical challenge and how did you solve. Resume grilling. Two rounds, first with mentor and second with manager. Grilled on fundamentals, beam bending, heat transfer, material choices, etc.

Just one recruiter screen and talk with hiring manager both done with microsoft teams. It was a little scary cause tesla cut a ton of interns around this time. Honestly not too hard but I got grilled a ton by the hiring manager and thought I did bad but still got a job?
