Tesla Mechanical Engineer interview questions

Contacted by the HR. Initially had 3 interviews over the phone, 1st by HR, 2nd by an Engineer and 3rd by the head of the group. Was called for an onsite interview and was asked to prepare a presentation.

Seriously, one of the worst experiences of my professional life. The recruiters are disrespectful and dismissive, and simply cannot follow through on plans. I have been in communication with a recruiter for months, and she will say thing such as "I will contact you in 3 days" and then never will contact me again. When I finally got an interview scheduled (through another recruiter), he never called me at the set time. After not receiving any email or phone call explaining why I emailed him back. He said something had come up, and rescheduled the interview for the next day. And then proceeded to not call me again, and again did not provide any explanation or apology. It's simply disrespectful of my time, and I do not wish to work at a company that teaches their employees that their time is so much more valuable than others that they do not have to have common courtesy or follow through on commitments. Tesla, remember that your recruiters are the first time your future employees get to see your companies culture. If I were you, I would be rather embarrassed about your recruiting teams, and understand that without your incredible reputation as a technological innovator (which may soon fade) your company would not be able to recruit talent.
