What this question tests
Product critique fundamentals: naming a specific flaw with reasoning, a simpler version of a broader product sense question.
How to approach it
- Pick a specific, real, well known product rather than a vague category.
- State the specific friction point users hit, grounded in an actual use case, not a general dislike.
- Explain the likely root cause, such as conflicting priorities between teams or a design that optimized for one metric at the expense of usability.
- Propose what a better design would look like, briefly.
- State how you would validate that the proposed fix actually helps, such as a specific usability metric.
What a strong answer includes
- Picks an example with a genuinely specific, well reasoned flaw rather than a generic complaint like 'it's ugly'.
- Connects the flaw to a plausible root cause, showing systems thinking rather than surface level critique.
- Proposes a concrete alternative design and a way to measure whether it actually improves the experience.
Common mistakes
- Naming a product but only expressing a personal preference without a specific, reasoned critique.
- Picking an example so obscure the interviewer cannot evaluate the reasoning.
Likely follow-up questions
- Why do you think this flaw has not already been fixed?
- What tradeoff would your proposed fix introduce?
