Phone App That Helps Supermarket Shoppers Choose and Buy Wine
Company: Meta
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are the product manager asked to design a mobile app that makes buying wine at a grocery store a better experience. Decide which shoppers the app should serve, identify the problems they run into, propose the product, choose what to build first, and explain how you would measure whether it works.
```hint Pick the shopper before the feature
A grocery wine aisle is a different setting from a specialist wine shop. Work out which shoppers there struggle most with their decision, and why, before you start listing features.
```
### Clarifying Questions
- Is the app built by one grocery chain for its own stores, or is it an independent app meant to work across many grocery stores?
- Should the product focus on the decision in the aisle, or also cover planning before the trip and ordering wine for pickup or delivery?
- Which outcome matters most to the grocer: higher wine sales, happier shoppers, or loyalty to the store?
- Which rules on selling alcohol apply where the store operates, for example age checks and limits on delivery?
### What a Strong Answer Covers
- A goal for the app that serves both the shopper and the grocery store.
- Distinct wine-shopper segments and a reasoned choice of which one to serve first.
- The chosen segment's specific pain points when picking a bottle in a grocery store.
- Solutions ranked by impact and effort, leading to a focused first version.
- Success metrics with guardrails, plus risks such as stock accuracy, trust in recommendations and alcohol rules.
### Follow-up Questions
- The grocer asks you to rank higher-margin bottles first in recommendations. How do you respond, and how do you protect shopper trust?
- How would your design change if the store has no reliable shelf-level stock data?
- After launch, shoppers scan many labels but wine sales do not rise. How do you interpret that, and what do you change?
- Suppose the request comes from Meta's CEO instead of a grocer: the app is Meta's own product, it has to work in any grocery store, and it may connect to Facebook or Instagram. Why should Meta in particular build it, which single goal would you set for the first version (engagement, purchases or revenue), and what else in your answer changes?
Overview: A product design prompt asking for a mobile app that improves how shoppers choose and buy wine in a grocery store. It tests user segmentation, identifying pain points at the shelf, prioritizing a focused first version, and defining success metrics, guardrails and risks for an in-store experience.
