Air Traffic Control:?

Short answer: In air traffic control systems, the Mediator Pattern can be used to handle communication between different planes and the control tower. The control tower acts as the mediator, relaying necessary information and ensuring that planes don’t directly communicate with each other, reducing the chances of collision or confusion.

Real-world example (ShopNest)

Use a GoF pattern in ShopNest only when it removes duplication or makes a change safer—explain the problem it solves in the interview.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
