Design a Sleep and Recovery Product Focused on Waking Up Refreshed
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Design a product whose purpose is to leave people feeling more rested.
```hint Define rested first
Feeling rested is not the same as sleeping longer. Decide which part of the problem you will own (sleep timing, sleep quality, winding down or daytime recovery) before you pick a user.
```
### Clarifying Questions
- Should the product build on Google hardware and services that already touch sleep, such as Fitbit, Pixel Watch or Android's Bedtime mode, or should I treat it as a standalone product?
- Is the goal better sleep at night, more energy during the day, or both?
- Are people with diagnosed sleep disorders in scope, or should the product stay a consumer wellness tool that refers them to clinicians?
- Is there a target market or platform, for example mobile-first in one country?
### What a Strong Answer Covers
- A working definition of "rested" and a clear choice of user segment, with the reason for it
- Pain points grounded in that segment's evening and morning routine, not generic sleep advice
- A small set of solutions prioritized into an MVP, with what is deferred and why
- A north-star metric tied to feeling rested, plus guardrails for privacy, notification fatigue and sleep anxiety
- Risks such as sensor accuracy, health claims and the handling of sensitive data
### Follow-up Questions
- How would you measure "feeling rested" when it is a subjective state?
- What would you do if users who track their sleep closely start sleeping worse because of the tracking?
- How would the MVP change if it had to work without any wearable?
Overview: A product design interview prompt asking you to design a product that helps people feel more rested. It tests how you define restfulness, choose a target user segment, identify pain points, prioritize solutions into an MVP and pick success metrics while handling sensitive health data.
