What this question tests
Foundational product design on a small, tangible business, useful for seeing structured thinking without a large company's complexity.
How to approach it
- Clarify the setting: a city tourist shop, a campus rental stand, or an app for an existing physical shop.
- Segment users: tourists wanting a few hours, commuters wanting daily rentals, and locals wanting weekend trips.
- Identify pain points: unclear pricing, bike availability, and the hassle of returns.
- Prioritize solving availability and simple pricing first, since they block the core rental job.
- Propose a solution: a real time bike map with tiered hourly and daily pricing shown upfront.
- Define success with rentals per bike per day and repeat rental rate.
What a strong answer includes
- Grounds the design in one clear user, tourists needing a few hours, rather than every possible rider.
- Names a concrete pain point, not knowing if a bike is available before walking over.
- Proposes a specific fix, a live availability map, instead of a vague 'better app'.
- Assumes an illustrative metric, like 3 rentals per bike per day as a healthy baseline.
Common mistakes
- Overcomplicates a small business problem with enterprise level features.
- Skips pricing clarity, which is the most common complaint in bike rental.
Likely follow-up questions
- How would you handle bikes left at the wrong location?
- What would your pricing model be for damage or late returns?
- How would you decide whether to add electric bikes to the fleet?
