Tesla Test Engineer interview questions

Phone interview, followed by a full-day on-site interview with 6 members of the team. Day started with a technical presentation on a topic of my choice. Interviews had lots of abstract questions testing fundamental concepts and general practical engineering knowledge. Overall it was a great experience - we just talked shop and the questions seemed more like formalities.

Applied directly through the website and was contacted the next day by a hiring manager, who informed me that I seemed to be an ideal candidate for the position for more than one department. After a brief phone interview, the hiring manager let me know that he needed to talk with the various group managers, and said that they wanted me to move forward to the next step, which was a practical exam. The exam was timed and done entirely online...which I did, within a reasonable amount of time. I sent the exam and NEVER received any follow up. I waited and followed up myself and never received any further communication. So after being told that I was an "ideal" candidate, I was just left in the dark. I don't feel that my performance on the practical exam could have been that bad, and although there were a few questions that I could not answer (which I already told the hiring manager that I did not have experience with prior to the test, and they seemed fine with it), I was able to answer everything else that I did have experience with. Completely unprofessional handling in that they did not even bother to let me know they decided not to move forward with me during the selection process.
