1. Contacted by recruiter. Went over my resume and job experience. 2. Contacted by senior engineer. Talked about my background. Very laid back. 3. Contacted by one of the managers. Talked about my past experience. Was asked for 1 or 2 specific examples. Phone interview was relatively easy. 4. Company flew me down to CA for an interview. Interview lasted for more than 5 hours in the Fremont, CA location. Interviewed with 5 managers/directors. Questions were very direct and mostly technical regarding my past experience. No written test or behavioral questions were asked. A couple of questions were asked about how would you persuade your manager to make changes even if they disagree. Each manager was very different. Got a bit nervous after a couple of hours. I did get a chance to go down on the floor and see Tesla Model S. Very cool! Overall, I would say questions were not very difficult if you are well prepared. The mental exhaustion can play a part in getting nervous after a couple of hours. Some of my observations: Very open environment, no cubicles. Judging by the amount of people still in the office after 6 p.m, expect to work long hours and weekends. Also, be prepared to wear different hats since the company is currently understaffed for what it needs to do in order to build quality cars. I felt that the interviewing process could have been better in terms of timing and structure. There is no cafeteria in the building but they do offer some snacks, pre-made sandwiches (for $) and provide free cereal, coffee, etc... Coming from a big organization and based on my questions to the managers, I felt that the company needs a more robust structure, set processes, and approval process. Overall, good experience.
