Product design: a delivery app built for kitchens and food sellers rather than diners
Company: Microsoft
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Design a food delivery app whose users are restaurant owners and food vendors, not the people ordering the food.
```hint Follow one order
Trace what happens in a busy kitchen or at a food stall from the moment an order comes in until a courier leaves with it. The friction along that path, and how it differs between a staffed restaurant and a vendor working alone, is where your design should start.
```
### Clarifying Questions
- Is this the seller side of a consumer delivery marketplace, where diners order from these businesses, or a supply app through which restaurants buy ingredients from food vendors?
- Does the platform provide couriers, or do the businesses deliver with their own staff?
- Which sellers matter most: established restaurants with counter staff, or small vendors such as food trucks, market stalls and home kitchens run by one or two people?
- Is this a new marketplace that starts with no sellers, or a replacement for an existing seller tool?
### What a Strong Answer Covers
- A clear call on what the app is for, and the goal it serves for both the sellers and the platform.
- Seller segments with different needs, from staffed restaurants to one-person vendors, and a justified focus.
- The seller's order journey during a rush and the pain points it exposes: missed orders, prep timing, items running out, courier handoff and payouts.
- Prioritized features with a first release that fits a noisy, busy kitchen.
- Seller-side success metrics, with guardrails such as cancellations, diner ratings and hours sellers stay open.
### Follow-up Questions
- Many small vendors already juggle orders from two or three delivery platforms. How does that change your design and your adoption plan?
- A vendor cooking alone cannot look at a screen mid-rush. How would order intake and status updates work for them?
- Your north-star metric is rising, but diner complaints about late food are rising too. How do you investigate?
Overview: A product design prompt asking for a food delivery app built for restaurant owners and food vendors instead of diners. It tests clarifying what the app is for, segmenting sellers from staffed restaurants to one-person stalls, mapping the order journey during a rush, cutting a first release and choosing seller-side success metrics.
