Interview questions [1]
Question 1
Tolerance stack up questions more technical based.
I applied through a recruiter. The process took 3 months. I interviewed at Tesla (Fremont, CA) in Jan 2016
Interview
I skipped the phone interview because I had a one on one with the recruiter when I was interning at Tesla. On site interview was at Fremont and involved a 45min presentation on a dimensional problem given to me, followed by 7 one on one's back to back with engineers and managers. I received a verbal offer a few weeks later and an official offer 2 months after that.
