Ex-Meta Engineer Shares 3 Key System Design Tips for 2026 🚀

System Design Interviews have changed, and if you’re still approaching them the old way, you’re already behind.

In this video, Fahim ul Haq, CEO of Educative and former software engineer at Facebook and Microsoft, shares the three most important tips you need to know to crush your system design interviews in 2026. Fahim has conducted countless interviews over the years at some of the world’s top tech companies, and he’s seen even the smartest engineers fall short. Not because they didn’t know how to code, but because they didn’t know how to communicate system design thinking effectively.

Fahim explains why today's interviews reward how you frame your decisions before you start diagramming. He dives into the importance of identifying non-negotiables, sketching a high-level architecture first, and clearly explaining the trade-offs behind every design choice.

If you’re prepping for a MAANG interview or applying to any senior engineering role, this is the kind of insider advice that separates good candidates from great ones.
