The interview process was quite drawn out. The recruiter took a while getting back to me, despite multiple teams showing interest in my profile.

Scheduling the phone interview took time, but the process was smooth. There was an online assessment as an initial screen; it was challenging but doable.

The phone screen itself was a pretty bad experience. Just as interviewing is a skill not everyone has, being an interviewer is also a skill not everyone has. The manager who interviewed me, I think, was not a good interviewer. He barely spoke, which is not what you'd expect in a phone interview.

I will think multiple times before interviewing for Tesla in the future.

Typical embedded software engineer programming interview question.
