Mobile App Marketplace Improvement: Choose a User Group and Prioritize Fixes
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
How would you improve the app store, the marketplace where people find, evaluate and install apps for their phones? Choose what to improve and for whom, describe your solution and explain how you would know it worked.
```hint Two sides of one marketplace
The store serves people looking for apps and the developers who publish them. Pick whose problem you solve first, then follow that person from search to listing to install and beyond, noting where things go wrong.
```
### Clarifying Questions
- Which store is in scope: Google Play, or mobile app stores in general?
- Should the improvement serve people installing apps, developers publishing them, or the store's own business?
- Phones only, or also other devices such as tablets, TVs and watches?
- What outcome matters most: more installs, better installs that people keep using, user trust, or developer revenue?
### What a Strong Answer Covers
- A clear choice of which side of the marketplace and which segment to improve for, with reasons
- The journey through discovery, evaluation, install and the first days of use, with the pain points at each step
- Prioritized improvements tied to those pain points, with their effects on the other side of the marketplace
- Metrics that capture the quality of installs as well as the count, plus guardrails for developers, trust and the store's revenue
- Risks such as gaming of rankings and reviews, fairness to small developers and regulatory scrutiny of store practices
### Follow-up Questions
- Your change helps people find better apps but moves installs away from small developers. How do you weigh that?
- Ratings and reviews are often manipulated. How would you make them more trustworthy without hiding genuine criticism?
- How would your answer change for a first-time smartphone owner with limited data and storage?
