Scenario

DoorDash observed that driver (Dasher) wait time at restaurants spiked last week versus the prior week.

Task

Walk through how you would debug the increase in Dasher wait time. Specify the metrics, segments, and analyses you would use to find the root cause. If you confirm restaurant understaffing is responsible, propose actions or experiments to address the problem.

Notes and expectations

• Decompose the end-to-end pickup latency funnel and identify which component(s) changed.
• Slice by restaurant, region, time of day, and order mix; distinguish product vs operational causes.
• If understaffing is the driver, outline experiments and operational tests to reduce wait time.
