Product Sense Case: Reimagining a Patrol Station for Its Primary Users
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
An interviewer gives you a one-line prompt: redesign a patrol station. Work out what kind of station is meant and whose experience you are improving, then propose a redesign: the problems it should solve, the changes you would make first, and how you would know it worked.
```hint Settle the word before the ideas
The phrase "patrol station" can be read in more than one way, and the users, their problems and the right metrics change completely with the reading. Confirm it, then pick one group of users and follow a single visit or workday from start to finish.
```
### Clarifying Questions
- Does "patrol station" mean a station that police or highway patrol officers work out of, or is a fuel (petrol) station meant?
- Whose experience should improve first: the people who work at the station every day, or the people who come to it?
- Is this a single existing station or a model to roll out across many, and is the building itself in scope or only the services and processes around it?
- What is driving the redesign (long waits, cost to run, safety, a new need), and are there budget or regulatory limits?
### What a Strong Answer Covers
- An explicit, confirmed reading of "patrol station" instead of a silent assumption.
- The station's users mapped out, one segment chosen with a reason, and that segment's visit or workday walked through step by step.
- Pain points tied to specific steps, with solutions that combine layout, process and digital tools, prioritized by impact and effort.
- A success metric tied to the chosen goal, plus guardrails such as safety, security and cost that the redesign must not worsen.
### Follow-up Questions
- Your redesign will be rolled out to stations of very different sizes. What stays standard, and what varies?
- Which change could you test at one station before committing to the full redesign, and how would you measure its effect?
- How would your design change if the interviewer meant the other reading of "patrol station"?
Overview: A Google product design prompt asking candidates to redesign a patrol station from a one-line brief. It tests resolving an ambiguous prompt, choosing a user segment, mapping that segment's journey and pain points, prioritizing physical, process and digital changes, and defining success metrics with guardrails.
