Product Strategy: Building a New Business Model to Upend Car Washing
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
How would you shake up the car wash industry? Describe the opportunity you would go after and what you would build.
```hint Map the industry first
Lay out the ways people get their cars clean today, from automated drive-through washes to washing at home, and note where each one costs the customer time, money or quality. Disruption usually starts with the customers incumbents serve worst.
```
### Clarifying Questions
- Am I entering as a new startup, or as an existing company that can use assets it already has?
- Should I focus on private car owners, on fleets such as rental, delivery and ride-hailing cars, or on both?
- Does disruption mean taking share from existing car washes, or does growing the market among people who rarely wash their car also count?
- Is there a particular geography in mind, given how much climate and water rules vary?
### What a Strong Answer Covers
- How the industry works today (its formats, how each makes money, where customers lose time or money) and what disruption means here
- A chosen target segment with specific pain points
- A concrete product or business model, compared against at least one alternative, with a clear reason incumbents would struggle to copy it
- A cheap first test and the metrics, including unit economics, that decide whether to scale
- Risks such as regulation, liability for damage, labor, seasonality and how incumbents would respond
### Follow-up Questions
- How would your answer change if the company entering were Google rather than a startup?
- What would you do if the large drive-through chains cut their membership prices in response?
- How does your idea hold up in a cold winter with salted roads?
