Your question is Study a Why Choice Between Apps. 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).
Pick an app. Your team would like to know why users choose this app instead of competitors, or why users choose a competitor instead. You have 3 weeks; how would you conduct the study?
Asked in the hypothetical case interview stage. The candidate chose Amazon as the app, with approximately 40 minutes to explain the approach.
Address how you would define the research objectives, recruit relevant participants, select qualitative and quantitative methods, compare Amazon with competitors, and turn findings into product recommendations. Explain how you would sequence the work across three weeks, manage scope, and determine whether the study produced actionable evidence.
