What this question tests
Tests product design for a sensitive, high-stakes domain inside a social platform, and whether the candidate handles trust, consent and emotional sensitivity alongside the usual design steps.
How to approach it
- Confirm scope: registering as a donor, matching living donors to patients, or raising awareness, since each has different users and risk.
- Segment users into potential donors, patients or families waiting for a match, and hospitals or registries that verify eligibility.
- Map the core pain point: most people intend to donate but never register because it isn't top of mind and the process feels bureaucratic.
- Design the flow as an in-app prompt that links to state registries, with social proof from friends who've registered, similar to Facebook's existing organ donor status feature.
- Handle sensitivity explicitly: opt-in visibility only, no public shaming, and clear medical disclaimers since Facebook isn't the registry of record.
- Define success as completed registrations through the flow, not likes or shares.
What a strong answer includes
- Builds on and differentiates from Facebook's existing organ donor status feature instead of reinventing it.
- Separates raising awareness, which can be viral and social, from completing registration, which needs to stay private and transactional.
- Proposes partnering with state DMV or registry APIs instead of having Facebook self-certify donor status.
- Uses illustrative numbers as assumptions: assume 2B MAU, 1% see the prompt in year one, 5% convert, roughly 1M new registrations.
Common mistakes
- Designing this like a normal growth feature while ignoring consent, medical accuracy and family notification.
- Making donor status public by default, which raises privacy concerns.
- Forgetting hospitals and registries as stakeholders who must verify any data collected.
Likely follow-up questions
- How would you measure long-term impact, not just registrations?
- How do you handle a user who wants to revoke donor status?
- Would you build this as a Facebook feature or a separate app?
