Welcome to your interview.
The question is on your right: Partnering Closely With Engineers. 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.
Tell me about a time you collaborated closely with engineers on a design project where there were constraints, trade-offs, or disagreement about the right solution. How did you work together, and what was the outcome?
