Why Good Coders Fail Coding Interviews (Even With DSA Knowledge)

Описание: Most coding interviews are not failed because of lack of knowledge.
They’re failed because of how you think under pressure.

In this video, I’ll show you five very common mistakes that good coders make in interviews —
And I am not talking about beginners — I am talking about good coders.

These are mistakes where:

Your solution is correct

Your code passes sample tests

And yet… the interviewer says “Let’s move on.”

We’ll look at real interview-style code examples, subtle edge cases, and the thinking traps that quietly eliminate strong candidates.

If you’ve ever thought:

“I knew this problem”

“My logic was right”

“I’ve solved harder questions before”

👉 This video is for you.

Watch till the end — the last section explains what interviewers are actually testing, and how to align your thinking with it.
