Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Come up with a new cane. Choose who it is for, which of their problems it solves, and why they would pick it over the canes available today.
```hint Walk through a day
People carry canes for very different reasons. Pick one group and follow a day of using the cane before you name any features.
```
### Clarifying Questions
- Is this a physical product we would make and sell, and may it connect to a phone or other devices, or is that open?
- Which goal matters most: user safety, independence, reaching people who avoid using a cane, or revenue?
- Are canes for walking support, long canes used by people who are blind or have low vision, and hiking sticks all in scope?
- Is there a price range, or a line on health claims such as medical-device regulation, that the design must stay within?
### What a Strong Answer Covers
- A comparison of the different people who use canes, and a justified choice of whom to design for first
- Pain points grounded in a realistic day of use for that group
- Ideas ranked by impact and effort, a defined first version and what is left out
- Success metrics with guardrails
- Risks specific to this group and product, such as safety, cost, stigma and regulation
### Follow-up Questions
- How would you test your riskiest assumption before committing to hardware?
- Who pays for it: the user, their family or a health insurer? How does that change the design and the price?
- Which group did you set aside, and what would you build differently for them?
