SOLID: ISP & DIP 🔥 | Java LLD for Amazon/Google Interviews

If you’re preparing for interviews at top product-based companies like Amazon, Google, or Microsoft, strong Low-Level Design fundamentals are extremely important.

In this video, we dive deep into two important design principles:

✔ Interface Segregation Principle (ISP)
✔ Dependency Inversion Principle (DIP)

You will learn:
• The core idea behind ISP and DIP
• Common mistakes developers make
• Bad vs Good design examples
• Proper Java implementation
• How to explain these concepts clearly in interviews
• What interviewers expect in LLD rounds

Understanding these principles helps you write:
• Clean code
• Loosely coupled systems
• Scalable architecture
• Maintainable applications

These concepts are frequently evaluated in SDE1 / SDE2 interviews and are foundational for advanced design discussions.

🚀 What’s Next?

From the next videos onwards, we will begin the Creational Design Patterns series.

We’ll cover patterns like:
• Factory Pattern
• Abstract Factory Pattern
• Builder Pattern
• Singleton Pattern
• Prototype Pattern

Each pattern will be explained with:
• Real-world use cases
• Java implementation
• Interview-focused explanations
• When and why to use them

So make sure you’re subscribed and stay connected 🚀
