I bombed a concurrency question in a trading firm interview — then had to learn 4 Design Patterns from scratch before my next round. This is Design Patterns Explained the way I wish someone had taught me: real code, real mistakes, no unexplained jargon. Design Patterns are one of the most important concepts to understand for Low-Level Design (LLD) and software engineering interviews. In this video, I’m starting a 3-part Design Patterns series where we’ll learn the most important design patterns using real software engineering examples — not generic car, truck, or vehicle examples. This is Part 1, where we cover the fundamentals of Design Patterns and Creational Design Patterns. We’ll go deep into 4 important Creational Design Patterns: • Singleton • Factory Method • Abstract Factory • Builder I’ll explain not just what each pattern is, but why you need it, the problem it solves, what the UML looks like, and how to recognize when to use it in an LLD interview. Examples covered in this video include: → Singleton with a Logger → Factory Method with Order Connectors → Abstract Factory with Stock Exchange Connectors → Builder with HTTP Request objects We’ll also cover the difference between Factory Method and Abstract Factory—one of the most commonly confusing parts of Design Patterns. 00:00 Introduction 01:34 Why Design Patterns Matter for Interviews 03:47 The 3 Types of Design Patterns 05:14 Creational Design Patterns 06:06 Singleton Pattern Explained 13:35 Factory Method Pattern 18:59 Abstract Factory Pattern 30:00 Builder Pattern 37:28 Recap: 4 Creational Design Patterns 38:42 Outro This series is designed for software engineers preparing for: • Low-Level Design interviews • LLD interviews • Software Engineering interviews • Machine Coding rounds • Design Patterns interviews 📚 DESIGN PATTERNS SERIES Part 1 → Creational Design Patterns Part 2 → Structural Design Patterns Part 3 → Behavioral Design Patterns If you're preparing for LLD interviews, I recommend watching the entire series in order.
