Go/No-Go Decision on Siting a New Grocery Store on One Neighborhood Block
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are asked to work out whether one particular block in your neighborhood would be a good place for a new grocery store. Walk through how you would make that call: what you would need to learn, where the evidence would come from, and what result would lead you to open there, pass, or look elsewhere.
```hint Two separate questions
Treat "is there enough grocery spending nearby" and "can a store on this exact block win enough of it" as separate questions; each needs different evidence.
```
### Clarifying Questions
- Who would open the store: an established chain choosing among candidate sites, an independent grocer, or a company trying a new small or checkout-free format?
- Is a space on the block already available, or is finding one part of the question?
- What does "suitable" mean to the decision maker: profitable within a set number of years, strategically valuable even at a loss, or serving residents who lack a nearby grocery?
- Is this a yes-or-no call on one block, or a ranking against other candidate sites?
### What a Strong Answer Covers
- A definition of success agreed before any analysis, and how it changes the evidence needed
- Demand in the store's realistic catchment: who lives, works or passes through nearby, what they spend and where they shop today
- The competition the store would face and why shoppers would switch, including sales lost at any sister stores close by
- Feasibility of the block itself: access, deliveries, space, rent and build-out cost, permits and local rules
- A decision rule that turns the evidence into open, pass or try another site, with the remaining uncertainty and how to reduce it
### Follow-up Questions
- If the numbers come out marginal, what cheap test could you run before signing a long lease?
- How would your analysis change if a large housing development or a transit stop is planned next to the block but not yet open?
- Which single finding would make you walk away even if demand looks strong?
Overview: A product strategy interview question that asks how you would decide whether one specific block in your neighborhood is a good location for a new grocery store. It tests how you frame a go or no-go decision, size local demand, weigh competition and site feasibility, and turn evidence into a clear recommendation.
