Apply product thinking to improve a restaurant you know well
Company: Nubank
Role: Product Manager

Difficulty: medium
Interview Round: Other
Choose a restaurant you love and walk through how you would make it better.
```hint Find what to protect
Before changing anything, say why this place is your favorite and what keeps people coming back. Then walk through a visit step by step and look for the moment that still goes wrong.
```
### Clarifying Questions
- Am I improving it as the owner, with the owner's budget and staff, or as an outside product designer who can propose apps and tools?
- Is the goal more revenue, more repeat visits, or a better experience for the diners who already come?
- Do improvements have to be digital, or are changes to the space, menu, staffing and operations also in scope?
- Should I cover dine-in only, or takeout and delivery as well?
### What a Strong Answer Covers
- A chosen restaurant and a clear statement of what makes it good, so improvements preserve it
- The restaurant's customers broken into segments, with one chosen for a reason
- Pain points found by walking the visit from deciding to go to leaving, prioritized by frequency and severity
- A small set of solutions, one prioritized with the restaurant's real constraints (space, kitchen, staff, budget) in mind
- Metrics a restaurant can actually track, and risks such as losing its character
### Follow-up Questions
- Your fix fills tables faster, but the kitchen falls behind at peak. What do you change?
- How would you test the improvement in a single restaurant, where a classic A/B test is not possible?
- Regulars say the place feels less personal after your change. How do you weigh that against the business gain?
