Choosing a product to build from unlimited global location data, privacy set aside
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Suppose you could use every kind of location data that exists anywhere in the world, and privacy was not a constraint. What product would you build, and why?
```hint Choose the problem before the data
Unlimited data makes almost anything possible, so the hard part is choosing. Look for a costly problem that persists mainly because nobody knows where people or things are right now.
```
### Clarifying Questions
- Does "all location data" include live, individual positions of people and vehicles, or only places, maps and historical movement patterns?
- Should the product build on Google's existing businesses such as Maps, or can it be a new standalone business?
- Is the aim the largest business opportunity, or the largest benefit to people even if revenue is modest?
- Does setting privacy aside also remove consent and security obligations, or only limits on what data can be collected and combined?
### What a Strong Answer Covers
- A goal and selection criteria stated before choosing, with a few candidate ideas compared against them
- A chosen user and problem that genuinely needs location data at this scale, rather than one that today's data already solves
- A concrete product: what it does, which data it fuses, how each user experiences it, and the first version to ship
- How success is measured and how the product creates value or revenue for Google
- Risks that remain even with privacy set aside, such as misuse, data gaps and trust, and how the design limits them
### Follow-up Questions
- Privacy rules come back tomorrow. Which parts of your product survive with aggregated or anonymized data, and which do not?
- How could a bad actor misuse your product, and what would you build to stop it?
- What is the smallest version you could ship first to test the riskiest assumption?
Overview: A product design and strategy interview question: if every kind of location data were available and privacy were not a constraint, what would you build? It tests how a PM sets selection criteria, picks a problem that truly needs such data, defines a first version and metrics, and handles the misuse risks that remain.
