This ensures that every concrete factory will implement the same methods, but each will provide platform-specific products. public interface IUIFactory Example code { IButton CreateButton(); ICheckbox CreateCheckbox(); } Real-world example (ShopNest) ShopNest’s NotificationFactory creates Email or SMS senders based on user preference. 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.
