Product Sense: Cutting Diner Wait Times at Busy Restaurants and Fast-Food Chains
Company: Swiggy
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are a product manager asked to design an app that reduces how long customers wait when they eat out, whether at sit-down restaurants or at food chains. Explain which waits you would target, who the app is for, what you would build first, and how you would know that waiting actually went down.
```hint Map where the minutes go
A meal out contains several separate waits, and a full-service restaurant loses time in different places than a counter-service chain does. Lay out the visit stage by stage, decide which wait hurts diners and the business most, and keep in mind that the restaurant, not the diner, controls most of what causes it.
```
### Clarifying Questions
- Which wait matters most here: getting a table or reaching the counter, getting food after ordering, or settling the bill?
- Are we designing for sit-down restaurants, quick-service chains where customers order at a counter, or both, and does takeaway count?
- Is the app used by diners, by restaurant staff and owners, or by both sides?
- Is this a standalone product, or part of an existing food ordering or table reservation platform that already has restaurants on it?
### What a Strong Answer Covers
- A breakdown of the visit into distinct waits for each type of outlet, and a reasoned choice of which wait to attack first
- Both sides of the problem: the diners who feel the wait and the restaurant operations that cause it, with a clear primary user and a plan for getting restaurants to adopt the product
- Solutions tied to specific pain points and prioritized by impact and effort, including what the restaurant must change for them to work
- Success metrics that measure the wait itself and the restaurant's business result, with guardrails, rather than generic download or active-user counts
- Risks such as inaccurate wait estimates, no-shows, gaming of a queue, and diners feeling rushed
### Follow-up Questions
- A popular restaurant tells you the crowd outside is free advertising and it has no reason to shorten it. How do you win it over?
- Quoted wait times keep turning out shorter than the real waits. What do you change in the product?
- How would your design change for a fast-food chain whose worst waits happen at the counter during the weekday lunch rush?
Overview: A product sense question about designing an app that shortens customer waits at sit-down restaurants and quick-service food chains. It tests whether a candidate can break a restaurant visit into separate waits, serve both diners and restaurant staff, prioritize solutions, and pick metrics that measure the wait itself.
