Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Design the restroom for one floor of an office building. Decide what the space needs to achieve, whose needs come first, which features matter most, and how you would know the design works once people are using it.
```hint Walk through one visit
Follow one visit from leaving the desk to returning to it, for each kind of person who uses or maintains the space, and note where time is lost or comfort breaks down.
```
### Clarifying Questions
- Is this a new fit-out or a redesign of an existing restroom, and is the location of the building's plumbing fixed?
- Roughly how many people work on the floor, and do visitors or clients use it as well?
- Should the design keep separate men's and women's rooms, add all-gender rooms, or is that our call?
- Which budget limits and code requirements, such as accessibility rules, should be treated as fixed?
### What a Strong Answer Covers
- A goal for the restroom that matters to the company as well as to the people using it
- The full set of users, including the people who clean and restock the space, with a stated priority
- Pain points across a visit, ranked by how often they occur and how much they hurt
- Ideas weighed on impact, cost and physical or regulatory constraints, leading to a prioritized design
- How the design is judged after the floor opens, and its main risks
### Follow-up Questions
- How would you decide how many toilets and sinks the floor needs?
- Which connected features, such as occupancy sensors or usage counters, would you include or leave out, and why?
- How would the design change if the floor mainly hosted visitors, such as a client briefing center?
