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).
If a key banking metric suddenly drops, how would you diagnose the cause and isolate whether it is a product, data, or model issue?
Explain a practical investigation workflow for an ambiguous KPI decline. Your response should define the metric and comparison window, validate the data pipeline and tracking, decompose the movement by relevant dimensions, test product and model hypotheses, and recommend actions with guardrails. Identify the evidence you would require before concluding that the decline reflects real customer or business behavior.
