Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Choose a product you know well and explain the user problem it solves, who benefits most, and which product decisions make it effective. Structure your response as a concise product analysis rather than a personal preference statement. Be prepared to discuss one limitation or improvement opportunity and how you would measure whether your proposed improvement creates value.
