That's literally the scene right now

Yeah man I just don't get it, what is up with these Hackathons and competitive coding.
If you want to hire me check how much I know.

Because those companies probably don't use django , react, angular.... So they give less damn about you knowing them.
But they do give a lot of damn about your logical skills. Hence they ask questions based on logic and algorithms right in almost all rounds.

There are companies that recruit on the basis of tech stack. Look out for them.

Companies are looking for the long run,when these technologies will be obsolete. What will you do then? That's why they want someone who has a strong grasp on fundamentals and can learn anything quickly
