Tesla Mechanical Engineer interview questions

The interview called me at 11 pm without any prior notice. Said working for Tesla is supposed to be demanding so I should be ready for an interview at all hours. Was very hard to understand him over the phone and he was very vague about the role and location. I am still not clear which position/location he was interviewing me for. Expected me to know everything about what Tesla does and how I fit into the company. Asked me some general questions about my current job. This was followed by some technical questions related to Tesla. Needless to say this interview caught me off guard and I performed poorly. I would recommend researching what the company does and being clear on what interview time suits you.

Screening Phone interview with recruiter. Had a good conversation regarding my work experience. Questions included what makes you a good engineer and what is important to you about a job. I was submitted to hiring manager, but no followup due to age filter
