Design a New ATM Tailored to Airport Travelers
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
The CEO of your company asks you to design a new ATM for the company's airport segment. Explain how you would take on the request: whom the machine should serve, which problems it should solve, what it would offer and how it would work, and how you would judge whether it succeeds.
```hint What changes at an airport
Compare a person standing at an airport ATM with someone at a neighborhood machine: their time, surroundings, distance from home and plans all differ. Let the sharpest of those differences decide what makes this machine new.

### Clarifying Questions
- What does the company do: is it a bank with its own ATM network, an ATM maker or operator, or another business that serves airports? This shapes how the machine earns money and what counts as success.
- Does "new ATM" mean a machine with different capabilities from the company's standard one, or a fresh deployment of the existing model?
- Do the airports in scope handle international flights, or only domestic ones?
- Is the main objective more withdrawals and fee revenue, better service for the company's own customers, or reaching new customers?
### What a Strong Answer Covers
- An explicit assumption about the company and the business objective, and how that choice shapes the design and the metrics.
- Airport user segments with different needs, and a reasoned choice of whom to design for first.
- The user's journey at the machine and pain points specific to airports, ranked with stated criteria.
- A concrete design that decides which standard ATM functions to keep, add or drop, weighing operating costs such as cash replenishment, extra currencies and maintenance.
- Success metrics, a pilot plan and guardrails.
### Follow-up Questions
- Travelers rely on cash less every year as cards and phone payments spread. Does an airport ATM still make sense, and how would that trend change your design?
- During the pilot, machines at the busiest airports keep running out of cash on peak travel days. What do you change?
- How would you choose which airports get the new machine first?
Overview: A product design interview question in which the CEO asks you to design a new ATM for the company's airport segment. It tests choosing an airport user segment, finding pain points a standard ATM ignores, deciding which functions to keep, add or drop given operating costs, and measuring success through a pilot.
