Interview Round: Other
Suppose a machine exists that can teleport a person 100 meters. What would you use it for, and how would you make money from it?
### Clarifying Questions
- Is 100 meters a fixed jump or a maximum range, and does it work in every direction, including up and down through floors?
- Does a trip need a machine at both ends, or can it send someone to any point in range?
- Can trips be chained through several machines to cover more than 100 meters?
- How large, costly and proven safe is each machine, and is it approved for public use?
### Part 1 — Use cases
Identify where a 100-meter jump creates real value, and choose which use cases to launch with.
```hint Find the costly short trips
Ask where a short trip is unusually slow, hard or risky today, and who bears that cost.
```
#### What This Part Should Cover
- A broad list of use cases across consumers, businesses and public settings
- Criteria for choosing what to launch first, and the use case chosen
- The users and pain points behind the chosen use case
### Part 2 — Monetization
Explain how the product makes money for the use cases you chose.
```hint List everyone who benefits
Name each party that gains when a trip disappears, then ask what each would pay for and how often.
```
#### What This Part Should Cover
- Who pays, for each chosen use case
- A pricing model and what the price is anchored to
- How revenue grows beyond the first use case, and the costs that shape it
### What a Strong Answer Covers
- Assumptions about the machine's limits stated before any solution
- A clear line from the chosen use cases to the paying customer and why they pay
- Safety, regulatory and public-trust risks of moving people this way
- Metrics that show whether the launch is working
### Follow-up Questions
- If each machine turns out to be very expensive to install, which use cases still work, and how does your pricing change?
- How would you prevent misuse, such as teleporting into a restricted area or past a security checkpoint?
- How would you decide between selling machines outright and charging for each trip?
Overview: A product strategy question about a hypothetical machine that teleports a person 100 meters, asking for its best use cases and how to make money from it. It tests stating assumptions, prioritizing use cases, identifying the paying customer and pricing a product with no precedent.
