Welcome to your interview.
The question is on your right: Designing a Useful Survey. 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.
You are planning a survey to inform a product decision, and the team wants the results to be credible, not just easy to collect. The main concern is that a poorly designed survey could overstate interest or hide real differences between user groups.
How would you design a survey so the results are actually useful and not misleading?
