What this question tests
Product design in the trust and safety space, identifying a specific harm and a proportionate product response.
How to approach it
- Clarify the type of safety, physical safety, e.g. meeting strangers, or digital safety, e.g. harassment and scams.
- Segment the risk, e.g. teens interacting with strangers, Marketplace buyers meeting sellers in person, or users targeted by scam messages.
- Pick one concrete risk to solve, e.g. in-person Marketplace meetups, since it has clear real-world stakes.
- Propose a feature, a verified public meetup location finder integrated into Marketplace chat, with optional location sharing to a trusted contact.
- Consider adoption, the feature must be low friction or usage will stay low despite the safety benefit.
- Define success metrics, adoption rate among Marketplace transactions and reported incident rate before and after.
What a strong answer includes
- Picks one specific, high-stakes safety scenario, in-person Marketplace meetups, rather than a vague 'make Facebook safer' claim.
- Proposes a concrete, low friction mechanism, suggested public meetup spots plus optional trusted-contact location sharing.
- Acknowledges the tension between safety features and privacy or friction, and designs around it, e.g. making location sharing opt-in.
- Sets a measurable safety outcome, reported incident rate, not just feature usage volume.
Common mistakes
- Proposing a vague catch-all safety feature without picking a specific scenario.
- Ignoring the tradeoff between safety features and added friction or privacy concerns.
- Measuring only adoption without tracking actual safety outcomes.
Likely follow-up questions
- How would you measure whether this actually made people safer.
- How would you balance privacy with safety in this feature.
- What would you prioritize next after this.
