Difficulty: medium
Interview Round: Other
How would you design and build a product that makes shared laundry work better for the people involved?
```hint Follow one load
Trace a single load from the moment someone carries the basket in to the moment the clothes leave, and mark every point where one person's behavior blocks, delays or surprises another.

### Clarifying Questions
- Does "shared" mean communal machines in an apartment building, a dorm or a laundromat, or roommates splitting the work of doing laundry?
- Am I building for the residents, the property owner who provides the machines, or the company that operates and services them?
- Can the solution change the machines themselves, for example by adding connectivity, or must it work with the machines already installed?
- Is this meant to be a Google product, for example tied to Google Home, or a standalone business?
### What a Strong Answer Covers
- A chosen setting and user segment, with the interests of residents, owners and operators kept distinct
- The specific coordination pain points across a load's journey: finding a free machine, knowing when a cycle ends, clothes left behind, payment, broken machines
- Solutions prioritized into a feasible first version, with attention to retrofitting old machines and poor connectivity in laundry rooms
- Fair-use rules for holding machines, queuing and moving other people's clothes
- Success metrics with guardrails, a business model, and risks such as adoption and privacy
### Follow-up Questions
- A resident's clothes sit in a finished dryer for an hour. What should your product do, and what should it never do?
- How would you deliver value in a building whose machines cannot be connected at all?
- Who pays for this product, and why would they?
Overview: A product design prompt about building a better experience for laundry that many people share, such as communal washers and dryers. It tests choosing a setting and user, mapping coordination pain points, prioritizing a feasible first version, designing fair-use rules, and defining success metrics and a business model.
