What this question tests
Tests product design for a health condition community: balancing practical daily needs with genuine peer support and trust.
How to approach it
- Define the user: people managing celiac disease, needing reliable gluten free information and connection with others facing the same daily challenges.
- Identify core needs: finding safe restaurants and products, and emotional support from others who understand the condition's daily friction.
- Propose the core features: a crowd sourced, verified gluten free restaurant and product database, plus moderated community discussion groups.
- Address trust and accuracy explicitly, since incorrect gluten free information could cause real health harm, requiring verification mechanisms.
- Define success: active community engagement and accuracy or trust ratings on shared restaurant and product information.
- State the assumption about whether the app is global or regionally focused, since food labeling and dining norms vary by country.
What a strong answer includes
- Grounds the design in real daily pain points, finding safe restaurants and reliable product labeling, which are the most common frustrations for people with celiac disease.
- Addresses the accuracy risk directly, proposing a verification or trust score system for crowd sourced gluten free claims, since wrong information has real health consequences.
- Builds genuine peer support through moderated small groups rather than an open feed, since health communities benefit from trusted, less public spaces.
- Sets a measurable goal, for example a stated accuracy rate on verified restaurant listings alongside active weekly community engagement.
Common mistakes
- Underestimating the real health stakes of inaccurate gluten free information, treating it like a generic dietary preference app.
- Ignoring the emotional support and community aspect in favor of only a restaurant database, missing half the stated need.
Likely follow-up questions
- How would you verify crowd sourced gluten free claims are actually accurate?
- How would you moderate the community to keep it a genuinely supportive space?
