Household Device Product Sense: Choosing and Justifying Three Priority Features
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are the product manager for a device used in the home. Which three features would you recommend for it, and why those three?
```hint Earn the three
Settle which device and which household you are designing for before naming any features, so each pick traces back to a specific problem and the three can be defended against the ones you left out.
```
### Clarifying Questions
- Do I choose the device, or is there a specific product in mind, such as a smart speaker, a thermostat, a robot vacuum or a kitchen appliance?
- Are these features for an existing device, or for the first version of a new one?
- Is the goal to sell more units, to increase how often the device is used, or to grow a paid connected service?
- Is there a target household, such as families with young children, roommates or older adults living alone?
### What a Strong Answer Covers
- A deliberate choice of device and household segment, with the reasoning stated
- Pain points drawn from how that household actually uses the device across a day
- A wider list of candidates narrowed to three with explicit criteria, including what was left out and why
- How each feature works, how the three serve a single goal, and the order in which they would ship
- Success metrics with guardrails, and risks such as privacy, data upkeep and added complexity
### Follow-up Questions
- If engineering can build only one of the three this year, which goes first and why?
- How would your three change for older adults living alone?
- How would you test demand for these features before committing to build them?
