Target Interface:?

Q: Target Interface:?

Short answer: The ITarget interface defines the expected interface that the client will use. It has a method Request() that the client expects to call. public interface ITarget Example code { void Request(); } 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 Define — one clear sentence (the short answer above). Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.
