Parking Facility Product Sense: Users, Journey, Features and Success Metrics
Company: Microsoft
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Design a parking lot. The prompt is deliberately open, so treat it as a product sense exercise: decide what kind of lot you are designing and for whom, find the problems those people face when they park there, and propose solutions. Explain how you would prioritize your ideas and how you would measure whether the design succeeds.
```hint Choose the lot first
A commuter garage downtown, an airport lot, a shopping-center lot and an office campus lot have different peak hours, stay lengths and goals. Pick one setting and one main group of drivers, then walk through their visit from arrival to exit.
```
### Clarifying Questions
- What kind of lot is it: a paid garage in a city center, a free lot at a shopping center, an airport or hospital lot, or an office campus lot?
- Are we building a new lot or improving an existing one, and does the scope cover the physical layout, the technology and services, or both?
- Whose goal comes first: drivers who want to park quickly, the operator who wants spaces filled and paid for, or the business the lot serves?
- Are there limits on budget, land area or construction that rule out some options?
### What a Strong Answer Covers
- A chosen setting and main user group, with the reason for the choice.
- The driver's visit from planning the trip to leaving the lot, with the pain at each step, plus the needs of the people who run the lot.
- Solutions spanning physical layout, operations and software, prioritized by impact and effort.
- Success metrics tied to the driver experience and the operator's economics, with safety and accessibility guardrails.
- Trade-offs and risks of the chosen solutions, including data collected about vehicles and what happens when equipment fails.
### Follow-up Questions
- The lot fills up by mid-morning on weekdays but is half empty by mid-afternoon. What would you change?
- How would your design change if this were a hospital parking lot?
- If you could ship only one digital feature first, which would it be and why?
Overview: An open-ended product sense exercise that asks a product manager candidate to design a parking lot. It tests choosing a setting and target users, mapping the driver's visit from arrival to exit, prioritizing physical and digital solutions, and defining success metrics and trade-offs.
