What are Design Patterns? All Types Explained in One Video | Low Level Design - Lesson 9

What are Design Patterns and why does every SDE interview ask about them?

In this video, I give you a complete introduction to Design Patterns. You'll learn what design patterns are, why they exist, and what are the 3 main categories:
🔹 Creational Design Patterns
🔹 Structural Design Patterns
🔹 Behavioural Design Patterns

This is a quick overview where I cover the names and purpose of each category. Detailed videos on individual patterns with Python code examples are coming next!

📚 This is part of my FREE Low Level Design (LLD) Course in Python. Each pattern will get its own dedicated video. Subscribe so you don't miss them!
