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. ⸻ 📌 Previously on this channel: In earlier videos, we discussed 👇 • What Design Patterns are (core idea & purpose) • Single Responsibility Principle (SRP) • Open–Closed Principle (OCP) • Liskov Substitution Principle (LSP) Watch these videos to strengthen your fundamentals 👇 🔗 What are Design Patterns? 👉 https://youtu.be/n_pQ2P6xbxQ 🔗 Single Responsibility Principle (SRP) & Open–Closed Principle (OCP) 👉 https://youtu.be/7v_4GJuv6d8 🔗 Liskov Substitution Principle (LSP) 👉 https://youtu.be/oAruFYjaZ1Y?si=WsbGxC5_ZRudH1W7 ⸻ 🚀 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 🚀 ⸻ If this video helped you: 👍 Like 💬 Comment your doubts or interview questions 🔔 Subscribe for more Low-Level Design & System Design content Your support motivates me to consistently create high-quality content for interview preparation and software design mastery.
