The saddest and funniest side of our industry is (atleast in India): someone works hard and makes it to the best colleges, do great projects on AI, ML; get a good score on Leetcode, codechef; gets a job in FAANG-like companies...

Changes colors in CSS and texts in HTML.

And, why is there so much emphasis on Data Structures and Algorithms? I mean, a little bit is fine, but why get obsessed with it when you never write algorithms in production code?

Now, don't tell me that, we use libraries and we should know what we are doing, no, we don't use algorithms even in libraries.

Now, before you tell me that MySQL uses B-tree for maintaining indexes, you really don't need to solve tricky questions to be able to understand how a B-tree works.

It's just absurd.

I know how to little bit on how design scalable systems.
I know how to write good code that is both modular and extensible.
I know how to mentor interns and turn them into employees.
I know how to mentor junior engineers (freshers) and help them get started.
Heck I can even invert a binary tree.

But some FAANG company would reject me because I cannot solve a very tricky dynamic programming question.
