But when the real interview starts, they realize something surprising: 👉 The interviewer is not looking for perfect answers. They are trying to understand how you think as an engineer . If you understand the interview process and what companies really evaluate, cracking interviews becomes much easier. Let’s break it down step by step.
Why Most Data Engineering Learners Stay Stuck for Years (And How Smart Professionals Break the Cycle)
Every year thousands of professionals start learning Data Engineering. They buy courses. They learn Spark. They practice SQL. They watch endless tutorials. Yet after months - sometimes years - many still feel the same frustration: 👉 “I know many tools, but I don’t feel job-ready.” This problem is more common than people admit.
