But that leaves me with a problem - I still need to turn this stack of 100 resumes into something I can be expected to work through, given the limited availability of my most expensive resource - time. I don't want to interview 100 candidates. I want to interview five. That means 19 out of 20 need to be eliminated before it even gets to the interview process.

The spelling heuristic gets rid of between 5 and 20%, right away. A lot of those resumes would also be caught by other heuristics (no ten page resumes, etc). Most of your concern cases would also fall to my other filters as well. And quite frankly, if a resume jumped out at me in a positive way, but it had three or four or five typos? I'd interview. It's not a hard and fast rule.

It's not as black and white as you think it is.

Between us, you should try to introduce automated Hacker Rank testing in your company.

It's a relevant filter and it's a terrific value for time.

A good old exercise to print number from 1 to 100 and then 100 to 1. That's the sort of things that get rid of half the candidates.
