With a big company like Google you can't just randomly hire someone without putting them through the rigorous interview process that can be months long (been there, done that), accomplishments or not (see the Homebrew dude).
The reason the failure to invert a binary tree story was notable was because the dude invented Homebrew. He was supposed to enter though the back door, but someone screwed up and made him go through the regular mechanism.
Why disrespect what’s been achieved here?
I think it's funny that you listed people who develop game engines, programming languages, and write algorithm and data structures textbooks.
Literally the people who could do the LeetCode algorithms and data structures problems in their sleep because it's actually relevant for their job.
In a previous life on a job site, the term was called measuring dicks but I digress.
