I can tell you Indian new graduates interview very well. They grind years on these DSA puzzles. But have very little engineering knowledge or skill in general. It's all about gaming the system here. I have literally seen people justifying lying on the resume, by feeding the job description to ChatGPT and let it come up with a resume. Yet, there's not much influential software coming out of India, where leetcode hards for graduates are the norm, but these graduates don't understand what a virtual machine is. On the other hand I have seen prolific open source contributors in the same age bracket (they contributed not to some web design project, but very much used cloud / system software) struggling to get a job, because they didn't do enough "DSA". I am not saying people of my country are dumb. Quite the contrary. I am saying when a measure becomes a target, it ceases to be good measure. That's the case with leetcode problems. It selects for people who can grind through it. Not the people who have other interesting things to do.
