Welcome to your interview.
The question is on your right: Battery In-House vs Outsource. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How would you structure a financial model to evaluate whether Rivian should manufacture a battery component in-house or outsource it to a third-party supplier?
