How these map to the role

These are marketing-analytics cases: a vague business question you frame into a metric and a measurement, and a budget or ROI recommendation you defend. The instinct they reward first is shaping the ambiguous question ("is marketing working?") into a well-defined analysis, and pushing past influenced numbers to incremental impact.

Each answer is a coaching walkthrough: a Sample answer (clarify → approach → a simulated back-and-forth → a clear call), then a Deep dive with illustrative example, then a Grading rubric.
