What this question tests
Tests breadth of product ideation plus judgment on prioritizing based on real need and privacy risk.
How to approach it
- Assume a small wearable or attachable tracker, similar to an AirTag or child locator, not a phone.
- Brainstorm segments: parents tracking young kids, families tracking elderly relatives with dementia, pet owners, lone workers in hazardous jobs, hikers.
- Narrow to the highest-need, lowest-creepiness case: elderly dementia safety monitoring, where consent runs through a caregiver.
- Design the core flow: geofence alerts, a low-battery or last-seen fallback, an SOS button, and a caregiver app view.
- Define success as alert response time, false geofence-alert rate, and caregiver retention.
What a strong answer includes
- Explicitly weighs the privacy and surveillance trade-off of a location tracker before picking a use case.
- Chooses a use case with clear consent, caregiver-managed, over more ethically fraught ones like tracking a partner.
- Grounds the idea in real products, Apple AirTag, Jiobit and GPS SmartSole, to show feasibility.
Common mistakes
- Listing surveillance-adjacent ideas like tracking a partner or employee without flagging consent and ethics.
- Not narrowing down to one prioritized use case before designing.
Likely follow-up questions
- How would you prevent misuse of this device for stalking?
- What's your battery-life versus accuracy trade-off?
