Company: Google
Role: Product Manager
Category: Analytics & Experimentation
Difficulty: medium
Interview Round: Other
Imagine you are a product manager at DoorDash. Which metrics would you treat as the most important for the company, and how would you organize them?
```hint Who makes one order work
A single delivery only succeeds when several different parties each do their part. Look for a number that rises only when all of them succeed, then decide what to watch for each party.
```
### Clarifying Questions
- Should the metrics cover the whole company, including grocery, convenience and other retail, or focus on restaurant delivery?
- Are these for a leadership dashboard that tracks overall company health, or for one product team's goals?
- Should the DashPass subscription and advertising sold to merchants be in scope, or only the core order flow?
- Is the company currently optimizing for growth or for profitability, which affects how I weigh order volume against profit per order?
### What a Strong Answer Covers
- DoorDash's goal and the needs of each side of the marketplace: consumers, merchants and Dashers
- One north-star metric, defended against alternatives such as gross order value, revenue and active users, with its blind spots named
- Supporting metrics for each side, organized along the order from browsing to delivery and repeat purchase, at local granularity
- Guardrails for delivery quality, Dasher earnings, merchant health and profit per order, split into leading and lagging indicators
### Follow-up Questions
- Your north star is growing while contribution profit per order is falling. What could explain that, and what would you check first?
- How would you notice a shortage of Dashers in one city before consumers start complaining?
- Which metrics would you add or replace if the focus moved to grocery delivery?
