If you know what you’re looking for, you just start skimming them and maybe ranking them based on your own rubric. If it’s an obvious “no” you can usually tell within 5 seconds skim. Once you have a handful of high ranking ones, stop, and talk to them. Repeat as necessary until you have a short list of people you’d want to hire. There might be 9900/10000 resumes you never even looked at and maybe one of them would have been slightly better but you can’t let perfection be the enemy of progress. Stand by your convictions of feeling the candidate is qualified and capable and meets what you expect and hire them, get back to business.
Having been in “talent shortage” mode for a long while I’d rather have 10000 resumes than 3. Having to pick one from a suboptimal selection is an awful position to be in, but sometimes a necessity.
