I was given a take-home style programming test.

I answered a few smaller programming questions and had to create a small application sample to demonstrate what I could do.

This application sample was not simple; it easily took half of a weekend.

This was reviewed by a manager, who decided if it was good enough to proceed to a phone screening/interview.

The call involved a discussion of the position and what the team does at Tesla, my history and experience, and eventually finished with another programming quiz on a shared coding site.

A second, similar phone interview with another manager on the team occurred a couple days later.

They didn't actually ask much outside of general programming and algorithm knowledge.

The interview was more a conversation about everything the team for this position does.
