Your question is What Was the Most User-Centric Thing You Designed. Take a moment with it on the right.
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).
Tell me about the most user-centric thing you designed and how it impacted the user experience.
Choose a specific product, feature, workflow, or service you personally shaped. Explain how you identified the user need, what design decisions you made, how you incorporated feedback, and how you evaluated the outcome. Clarify your individual contribution, the trade-offs you considered, and what you would improve in retrospect.
