Short answer: If the object’s state is large or changes frequently, the Memento Pattern can result in significant memory usage, as you need to store many copies of the state (each memento).

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.
