It's just like dating - have you tried it lately? Dating Apps has made the issue even worse - so "better" hiring platform is not a viable solution either.

The quickest hires IMHO are via referrals - but this is sort like arranged marriages/dates and it comes with it's own set of issues (nepotism etc).

I think companies need to have dedicated HR / Recruiters (or hire headhunters) to cut down on such frustrations. But the problem is tech hires, unlike construction / temp hires require high touch interviews with department heads etc. Add flood of resumes (now that WFH is a thing) and it's so difficult to speed up the process since it's costly to hire the wrong candidate.
