Tesla Firmware Engineer interview questions

Contacted by a recruiter on LinkedIn. After initial chat, was sent a test to do online. The test was really well written, and was a lot of fun to solve. Following that, the recruiter scheduled two technical interviews spaced over 2-3 days. The interviews were standard coding challenges. Nothing specific to firmware really. Recruiter had the courtesy to let me know that I was rejected, including what I did well and where I was expected to have dome better.
