Your question is Simplifying Workflows and Measuring Success. 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).
Walk me through a project where you simplified a complex workflow. What did you change and why? Tell me about a time you disagreed with a PM or engineer. How did you resolve it? How do you decide what to ship when time is limited? Describe a design decision you made that was unpopular at first but proved right. How do you measure success for a UX change? Tell me about a time you used research or data to change direction.
