### Clarifying Questions
- What does the product carry: small packages sent across town by people and small businesses, orders from restaurants and stores, or larger shipments for companies?
- Who pays for a delivery: the sender, the recipient, or a business on a contract?
- Do couriers come from 99's existing car and motorcycle drivers, or from a separate fleet?
- Is the business still expanding city by city, or national and expected to make money now?
### What a Strong Answer Covers
- The product's goal for senders, recipients, couriers and 99 itself, including how it relates to the ride business
- A precisely defined north-star metric and why it beats raw order volume or revenue
- Supporting metrics for demand, courier supply and marketplace balance, delivery reliability, and unit economics
- Guardrails for safety, lost or damaged items, courier earnings and effects on ride supply
- Reading the metrics by city, time of day and customer type, and in light of the business's stage
### Follow-up Questions
- Delivery orders grew quickly, but ride pickup times got worse in the same cities. How would you decide whether the delivery business is succeeding?
- The margin per delivery is negative in most cities. Which metrics would tell you whether that is acceptable for now?
- A large merchant wants a contract with guaranteed delivery times. How would that change the metrics you report?
