Oh, I'm not disagreeing on the opportunity available. You are, to quote Hermes from Futurama, technically correct (the best kind).

I do think that this problem is up there with world peace.

Technology, as wonderful as it is, is not going to change employers, or rather, certain ideas often found in employers.

Why haven't DICE or Indeed.com or whoever seem to have done any work on that front? I'm thinking the ROI isn't there.

Considering that it costs 20% for a match by a recruitment company, there is enourmous ROI for a program like that. It would almost be as good as the ability to print money.

Not to mention the cost you could get for the unemployed to sign up ("It costs you on average 2k/month not to use our service").

Enormous ROI for the company, not so much the recruiter, who enjoys the moral hazard of getting paid either way, whether their filtering sucks or not.

Sure, if the company hires the applicant.

Which leaves the question of why no work appears to be done in this direction.
