What this question tests
Product critique skill applied to a familiar app category, checking whether you can identify a specific, real problem and a grounded improvement, not a generic wishlist.
How to approach it
- Pick one specific real estate app you actually know well, like Zillow, rather than speaking about the category abstractly.
- State the problem it solves: helping buyers and renters search listings and estimate home values in one place.
- Identify a specific weakness: automated home value estimates, like Zestimates, are often inaccurate in less liquid or unique housing markets, undermining user trust.
- Prioritize estimate accuracy and transparency over adding new browsing features, since trust in the core value estimate is foundational to the product's usefulness.
- Propose a fix: show a confidence range instead of a single point estimate, and disclose the data sources and recent comparable sales driving that specific number.
- Define success as reduced user-reported disagreement with estimates and increased engagement with the comparable sales data shown alongside them.
What a strong answer includes
- Picks a specific, well-known app and names a real, documented weakness, automated estimate inaccuracy, rather than a vague critique.
- Proposes a specific fix, a confidence range plus transparent comparable data, rather than just 'make it more accurate'.
- Ties success to trust-related metrics, disagreement rate and engagement with supporting data, appropriate for the identified problem.
Common mistakes
- Speaking about real estate apps abstractly instead of committing to one specific, familiar app.
- Proposing a vague improvement like 'better UI' instead of addressing a real, specific functional weakness.
Likely follow-up questions
- How would you rebuild trust with users who've been shown inaccurate estimates before?
- How would you gather better data to improve estimate accuracy in less liquid markets?
