> There's absolutely no correlation between resume quality and candidate performance
I don't think that's entirely true. The resume is a product of a potential hire, and it gives off the first impression of their organizational and writing skills. While it shouldn't be the _only_ deciding factor, that first impression is an important signal for a hiring manager who has to filter potentially hundreds of candidates.
That's like saying a first date is in indication of a couples future. It's a bit silly. Sure, if it's absolutely chock-full of errors that could be a sign, but one or two are the kind of things you're supposed to ignore.
> that first impression is an important signal for a hiring manager
Only because people have been trained to judge others based on petty things, so people have responded in kind. Not because it's actually a valuable effort, but to give people one less reason to throw it in the "No" pile.
