Chain Setup:?

Short answer: In the Program class, we set up a chain of responsibility by calling SetNext() on the infoLogger and passing it the errorLogger. This ensures that the InfoLogger will process log messages with the Info level, while the ErrorLogger will handle Error level messages.

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

2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
