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).
How do you identify the key drivers behind a change in operating margin? Explain how you would define the metric, decompose its movement into revenue, cost, mix, and expense drivers, and distinguish business effects from accounting or timing effects. Describe the data you would need and how you would present the findings to decision-makers.
