Your question is Analyze Sudden Drop in MAUs. 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 how you would analyze a sudden drop in monthly active users for our product.
Explain how you would first validate that the movement is real, define the metric precisely, and distinguish a tracking issue from a genuine engagement decline. Then describe how you would decompose the change by user, platform, geography, acquisition source, and lifecycle cohort, prioritize hypotheses, and recommend next steps. State which data sources and supporting metrics you would use, how you would communicate uncertainty, and what actions you would take based on the findings.
