Tesla Software Engineer, Backend interview questions

I was reached out by a HR recruiter on Linkedin. He talked to me over the phone to get some information about my experience and what I'm looking for in the next role. He set a call with the technical recruiter in a few days. Awful technical recruiter call. It was a video call where the technical recruiter (the engineering manager of the team they were hiring) talked to me. He asked me about my background and within a few minutes, I saw him distracted and not interested to talk or ask any more questions. I wouldn't have upset him by talking about my background as they already had my resume and I was just elaborating what was mentioned on the resume. Very unprofessional of him to not be attentive on a video call. WORST EXPERIENCE. Would never consider to interview for the company again.

Background: 4 Years of experience as Software Engineer First round: Recruiter call for 30 minutes discussing my background and my expectations from next role. Codility: Was given online assessment containing 2 programming questions and 1 sql question. After test, recruiter contacted me in couple days asking me that they want to move forward. But then I was handed off to another recruiter who works for team in Seattle. I was asked to come onsite in Fremont with some video interviews with folks in Seattle. Onsite consisted of 5 rounds: Chat with PM -> team fit style questions Lunch interview tech round -> data modelling question chat with manager -> team fit style questions tech round -> interviewer was in no mood for interview. He was really tired. Asked me some simple string manipulation question for the sake of it. Finished interview 15 minutes before scheduled. At that point itself I knew I am not getting this job. I cannot share any specific questions due to NDA. But overall, it was not a very difficult interview.
