Build a challenger to a product you use daily: wedge, first features and metrics
Company: Meta
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Pick a popular product you use regularly and explain why it works for you. Then design a product to compete with it: who it is for, how it wins, and which features you would build first.
```hint Find the wedge
A newcomer rarely wins by copying the incumbent's best features. Look for a group of users, or a job, that the product you picked serves poorly.
```
### Clarifying Questions
- Is the competitor launched by a small startup, or by a large company that could bundle it with products it already has?
- Should the challenger try to win the incumbent's current users, or people the incumbent does not reach today?
- May I pick any category, including a business tool, or should it be a consumer product?
### What a Strong Answer Covers
- A clear account of the user need the chosen product meets and why it succeeds
- Specific weaknesses or underserved segments of that product, grounded in real use
- A positioning that gives users a reason to switch, rather than a feature-for-feature copy
- A prioritized first release with explicit trade-offs and a list of what waits
- Success metrics, plus a plan for the incumbent's response
### Follow-up Questions
- The incumbent copies your headline feature soon after you launch. What keeps your users?
- How would you win your first users when the incumbent owns the category's brand and its app store searches?
- If you were the incumbent's PM, how would you defend against the competitor you just designed?
Overview: A product sense prompt where you pick a popular product you use, explain why it works, and design a competitor to it. It tests finding a segment or job the incumbent serves poorly, giving users a reason to switch, prioritizing a focused first release, and defining metrics for a challenger.
