That's part of the art. It's obvious to anyone who knows it and mysterious and ineffable to anyone who doesn't.
The meta-point is that corporate developers have been through the hiring machine and are supposed to know these things.
Stories like this imply that in fact they don't.
The hiring machine merely ensures that they can leetcode their way out of an interview and into the job. It doesn't care about what they're supposed to know :)
