I applied online. The process took 1 week. I interviewed at Tesla in Feb 2018
Interview
I applied through Tesla's online portal with my resume and a cover letter. Soon afterwards a recruiter reached out. He wanted to schedule a talk about 1 hour from sending the email, which was a fast turnaround but I obliged. He then missed our call and the emailed to reschedule to an hour later, which he ALSO missed, without sending an email to notify me that he would be missing it. We then rescheduled to the next day, when he called me about 20 minutes late. The interview itself went fine - he asked fairly standard behavioral questions, although about halfway through we started discussing things that were way off topic - sports, travel, etc. To make sure that I was a good fit, after the interview he asked for me to go line by line on the job requirements and write why I met the requirement. After emailing the recruiter this information, he completely ghosted me - no response despite 3 followup emails. Would have been nice to at least send a rejection email. Overall a pretty terrible first impression of Tesla.
I applied through college or university. The process took 4 weeks. I interviewed at Tesla (San Francisco, CA) in Sep 2017
Interview
Three round. First phone call, then modeling test, then final round. The modeling test is an optimization question about the energy storage. The question is vogue and allow creation. It requires coding in python, matlab, etc. And for the final round, the asked a lot about the models and how you can improve it.
