Choose a Wearable Device Opportunity and Define Its First Version
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Identify the best product to build in wearable technology. Decide what the device is, who would wear it and for what problem, why that opportunity beats the others you considered, what its first version would include, and how you would measure whether it succeeds.
```hint Compare opportunities before designing one
Wearables can sit on the wrist, ears, eyes, fingers or skin. List a few candidate problems, score them on how painful the problem is, who would pay, and whether something worn on the body is really the best way to solve it, then commit to one.

### Clarifying Questions
- Does "the wearable technology" refer to a specific technology the company already has and wants a product for, or to wearables as a category?
- Should the product be one Google would build and sell, drawing on its existing devices and services, or should you reason as an independent company?
- Is the aim a mass-market consumer device, or is a focused market such as health care or workplace safety acceptable?
- Are there limits on price, time to launch, or whether the product may need approval as a medical device?
### What a Strong Answer Covers
- A scoped interpretation of the prompt and a clear objective for the product.
- A landscape of wearable form factors and user segments, with a structured comparison that justifies the chosen opportunity.
- Pain points of the chosen users mapped to a focused first version, with features prioritized and deliberate cuts named.
- Business model and go-to-market, including who pays when the wearer and the buyer differ.
- Success metrics with guardrails, and the main risks such as accuracy, battery life, privacy, regulation and social acceptance.
### Follow-up Questions
- What evidence would make you switch to a different opportunity from your list?
- How would your design change if the person who buys the device is not the person who wears it?
- What would you test before building any new hardware?
Overview: An open product sense question asking a candidate to identify the best product to build in wearable technology. It tests scoping a broad prompt, comparing form factors and user segments, choosing and designing a focused first version, and defining success metrics and risks such as accuracy, battery life and privacy.
