Who cares if it's carmack or buddha?
it's still brilliant code written by creative people, who can do stuff beyond memory copy/pasting code from other people
But that's the problem. If a few hours of exercise can dramatically change someone's results then it's not an acid test and it speaks poorly to the quality of whatever team the candidate would be joining.
All interviews are two way streets and the problem is everyone knows what kind of results pass through the leet code filter and so if it's a bad process, perhaps your best candidates will decline to proceed or accept.
You want people whose time is more valuable than your money. That's kinda the whole point of employee/employer social arrangements.
Zuckerberg was able to build Facebook because he got a good education and understood graph theory enough to apply it to social networks.
In the past, the only people who really understood concepts like graphs were people who endured rigorous four-year computer science curriculums. And only top students at elite schools would learn this. The average CS graduate has a very poor understanding of fundamental data structures and algorithms.
But with Leetcode, anyone can solve 5-10 graph problems and obtain the same knowledge. It's extremely efficient. In a couple of days, you can learn what used to take years.
Facebook accounts have a friends list. Why would you need to understand graph theory.
// don't change this number, not sure why it works...
not an exact quote but something like that
and the people who wrote it didn't spend thousands of hours memorizing the same stupid leetcode exercises to pass lame interviews for 6 figures job, they worked on real projects
tell me the fast inverse square root from Carmack would have been praised in an interview...
