How to Learn System Design: The Essential Resource List

System design interviews can be tough. I remember when I first started preparing, it felt like trying to build a skyscraper with LEGOs. I had individual pieces, but no clear blueprint on how to put them together.

That’s why I've compiled a list of essential resources to help you navigate the world of system design. These are the resources I wish I had when I started. Let’s dive in, shall we?

Why System Design Matters

System design is about creating scalable, reliable, and efficient systems. Whether you're building a social media platform or a complex e-commerce site, understanding system design principles is key.

System design isn’t just for architects or senior engineers. Everyone benefits from thinking about the big picture, which is why it's a common part of technical interviews. By the way, have you seen our list of companies with LLD interview questions? It’s a great way to get a feel for what’s expected.
