UX Teardown of an App: Usefulness, Clarity, Honesty, Visual Appeal, Innovation
Company: Amazon
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Choose an app, or take the one the interviewer names, and judge how well its design holds up against five principles: innovative, understandable, aesthetic, honest and useful. For each principle, explain what you observe in the app and how well it does, then give an overall judgment of where the design is strongest and where it is weakest.
```hint Make each principle testable
The five words are vague on their own. Before judging, turn each one into something you can check in the app, such as a task a first-time user has to finish, or a moment where the app's interests and the user's interests pull apart.
```
### Clarifying Questions
- Should I choose the app, or will you name one? If I choose, would you like it to be one of Amazon's own apps?
- Which user and task should the evaluation center on: a first-time user, a frequent user, or a particular flow such as checkout?
- Should the five principles count equally, or should I weight them for this app's purpose?
- Should I judge the app on one platform, such as its phone version, or also compare its web version?
### What a Strong Answer Covers
- A chosen app with a defined target user and core task, so every judgment has a reference point.
- Each principle turned into concrete, observable criteria and applied with specific evidence from the app's screens and flows.
- Tensions between principles, such as novelty against clarity, a clean look against information density, and business goals against honesty.
- An overall assessment that ranks strengths and weaknesses and links improvements to the weakest findings.
- Ways to check the critique with research or data rather than personal taste alone.
### Follow-up Questions
- Which single change would you make first, and how would you measure whether it helped?
- If the app's revenue depends on a pattern you rated as dishonest, how would you make the case to change it?
- How would your evaluation differ for a first-time user compared with someone who opens the app every day?
Overview: A product design question that asks you to pick an app and judge its design on five qualities: whether it is useful, understandable, honest, aesthetic and innovative. It tests turning vague principles into observable criteria, citing evidence from real flows, weighing trade-offs between principles, and reaching a clear overall judgment.
