Summary

PM interview at DoorDash with a product sense question about the post-order experience. Pretty open-ended and I wasn't totally sure how deep they wanted me to go.

I started rattling off things like late deliveries and out-of-stock items, which felt obvious the moment I said them.

Suggested Approach

Structure your answer around the post-order customer journey, from order confirmation to delivery completion, and identify potential failure points at each stage. Prioritize the most critical issues based on impact on customer experience and business metrics, and briefly suggest how you would measure and mitigate them.

Pro tip: Show that you think holistically about the three-sided marketplace—customers, Dashers, and merchants—and how a failure on one side affects the others. Also, tie your analysis to key metrics like delivery time, order accuracy, and customer satisfaction to demonstrate product sense.

1. Map the post-order journey

Break down the process into stages: order confirmation, merchant acceptance and preparation, Dasher assignment and pickup, delivery, and post-delivery. This ensures comprehensive coverage.

2. Identify potential failure points at each stage

For each stage, brainstorm what could go wrong, such as order rejection, long preparation times, Dasher unavailability, delivery delays, or incorrect drop-off.

3. Prioritize based on impact and likelihood

Assess which failures are most critical in terms of frequency, customer impact, and business metrics (e.g., delivery time, cancellation rate, CSAT). Focus on high-impact areas.

4. Propose mitigation strategies and metrics

For top issues, suggest potential solutions (e.g., better Dasher allocation algorithms, real-time tracking, proactive communication) and how you would measure success (e.g., reduction in delivery time, increase in on-time delivery rate).

Key Points to Mention

  • Order accuracy and completeness (missing items, wrong items)
  • Delivery time variability and delays due to traffic, weather, or Dasher issues
  • Dasher availability and assignment efficiency, especially during peak times
  • Merchant-related issues: order rejection, long preparation times, store closures
  • Communication gaps: lack of real-time updates, difficulty contacting support
  • Food quality and temperature maintenance during delivery
