What is method overloading?

Short answer: Same method name with different parameters in the same class. Enables compile-time polymorphism. class MathHelper

Example code

{
public int Multiply(int a, int b) => a * b;
public int Multiply(int a, int b, int c) => a * b * c; // Overloaded }

Real-world example (ShopNest)

Think of ShopNest’s Product, Cart, and Order classes: each object holds data + behavior, so pricing rules stay next to the data they use.

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.
