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).
You're supporting a payments business that has seen transaction volume fall in one merchant category. Leadership wants to know whether the drop reflects weaker marketing performance or a broader shift in consumer spending.
If we observe a 10% drop in transaction volume for a specific merchant category, how would you investigate whether this is a marketing issue or a broader market trend?
