Orders are growing while repeat purchase rate falls. Diagnose the change.
Build a defensible answer, then pressure-test it in the same workspace where you can save the attempt.

Start with a position
Give the interviewer your decision before the framework.
For “Orders are growing while repeat purchase rate falls. Diagnose the change.” at Amazon, I would define the intended outcome for a clearly defined Amazon customer whose repeated job is underserved, build a driver tree to customer outcome and repeat behavior, segment before explaining the movement, and make the decision only after checking quality, cost-to-serve, trust, and operational defects.
Preview the reasoning
Three moves to make the answer concrete.
Build the metric tree
- Segment before explaining
- Compare at least one credible alternative.
Segment before explaining
- Include contribution economics and operational guardrails
- Compare at least one credible alternative.
Measurement check
A metric is useful only when it changes the decision.
- North star
- customer outcome and repeat behaviorMeasures the repeated user or customer outcome, not mere feature activity.
- Diagnostic
- controllable input metric movementExplains whether quality and the critical journey improved for the intended segment.
- Guardrail
- quality, cost-to-serve, trust, and operational defectsMakes the principal downside observable: a locally successful launch that damages trust, unit economics, employees, sellers, or downstream communities at scale.
Interviewer pressure test
Do not stop when the first answer sounds polished.
- Why prioritize a clearly defined Amazon customer whose repeated job is underserved, and who did you explicitly defer?
- How would your answer change with two weeks, three engineers, or a tenfold scale increase?
- What is the strongest rejected alternative and when would it win?
