Got call from the recruiter through an employee referral. Had a short talk and explained to him my background and later he send me the job description of "Staff Firmware Engineer". I already took the coding challenge couple of weeks earlier for another Tesla Firmware position, so he let me skip the coding challenge. Then he setup a phone interview with the Director of the team. The interview was scheduled for 10AM but right before that, the recruiter emailed me and rescheduled it for 530PM in the evening. 530PM passed but no one called and finally got the call at around 615PM. The person was in a rush but had a quick conversation. A week later after poking the recruiter, he setup me up with an informal 1 hour long onsite interview with the team. It was 3 different Managers from Tesla Energy team who interviewed me together and talked about very general subjects regarding my past projects and some design basics. One of them was really cool, I could see him putting a lot of thoughts before asking me any question and also paying attention to what I am saying. The 2nd person was ok and was asking me questions as I went along. The third one somehow gave me a very weird vibe and I didn't like his attitude too much. After the interview I reached out to the recruiter and by that time I had an offer from one of their competitor. At that time the recruiter told me that the position available is not Staff but a general "Firmware Engineer". The fact that I already had 5+ years of Firmware experience and another offer from a competitor for a Staff position so I declined Tesla and moved on. Honestly I am a bit surprised as to how the recruiter first shared a Staff position's job description and later said they want to move forward as just a "Firmware Engineer" and not even a Senior position. Personally I didn't expect it from a company like Tesla.
