There are recruiting agencies who have tried this method: "Use AI to match the most relevant candidates to the job spec you gave us."
Spoiler alert, it doesn't work. The result is a mountain of overfitted garbage, with keyword spamming like there was no tomorrow. And they all find the same unqualified candidates.
If you're a recruiter, you're supposed to find the qualified, non-trivial to surface candidates. And yes, unfortunately that means it's a lot of hard work. (The top-notch agency recruiters value their personally built candidate networks for a good reason.)
