Product (Pizza):?

Short answer: The Pizza class is the Product that we are constructing. It has properties for Dough, Sauce, and a list of Toppings. The ToString() method is overridden to provide a string representation of the pizza. public class Pizza

Example code

{
public string Dough { get; set; }
public string Sauce { get; set; }
public List<string> Toppings { get; } = new List<string>();
public override string ToString() => $"Pizza with {Dough} dough, {Sauce} sauce and toppings: {string.Join(", ", Toppings)}"; }

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.
