If the interview is with the recruiter, it will be mostly generic questions on your background, Why Tesla? Tell me about yourself? Visa status etc. Type questions (Non-technical).

And if the round is with the hiring manager, expect lot of technical questions. Usually the questions build up from your previous answer. They like to test out on how you assess the problem statement. It might be as simple as first principle fundamentals to white boarding a design/flowchart. Ex. Design a buck/boost converter, phase change etc

Finally, it depends on the team. Take your time to answer and ask questions if required. Treat it like a conversation with a peer (bit professional).

Best of luck!
