🚨 Why Most Backend Engineers Fail Interviews (And How You Won’t)
If you struggle to answer real-world system design and backend questions, you’re not alone.
Most engineers fail—not because they lack coding skills—but because they miss core architectural thinking.
This guide fixes that.
💡 What You’ll Learn
This is not theory. This is how real senior engineers think and answer in interviews.
Inside, you’ll learn how to:
✔ Break down vague requirements with clarity
