Day 5 solving leetcode #dsa #coding #faang

Added: 2026-05-26

[00:00:00]Day five of solving lead code and today I'm solving reorder linked list. But before I start I saw a comment on my previous video asking, "Does DSA even help?" And honestly, I used to think the same.

[00:00:14]As a data engineer I'm not reversing linked list or detecting cycles in my day-to-day work.

[00:00:19]So for a long time, DSA felt unnecessary. But now that I'm actually practicing consistently, I think DSA helps in different ways. It trains you how to think clearly under pressure, to break down a problem, to identify patterns, to communicate your approach, and to come up with a working solution within limited time. Because in interviews, they are not only checking if you can code. They are actually checking how you think.

[00:00:46]And if DSA didn't matter at all, why are top product-based companies still asking these questions even in the age of AI and all these advanced tools?

[00:00:54]That's my opinion, at least.

[00:00:57]What's your take on this? Do you think DSA is still relevant in 2026?
