One recruiting screen / interview and then a person interview with two workers. They asked the basic questions and behavior questions. It wasn't too hard nor difficult. If you prep, you'll do fine.

after applying, I received an email from their nationwide recruiter asking for my availability for the next 2 weeks to set up an interview. I answered and received no response. The following Monday I got the same email from the same recruiter, and this time my response got a response. I came in and interviewed, it took about a half hour and was told that the GM would enter her notes into the system and then Tesla would decide from there if there would be a second interview. At the end of the week I got an email that they were moving forward with someone more closely aligned, and was encouraged to try again in the future.
