I asked this on reddit. How much of a proliferation do recruiters have on the job market? For example, in major cities, recruiters can find out information about every real job in the city and essentially build a relationship with every major company out there. In theory, they can own the job market. The HR recruiters don't have the time to scan over all the resumes they get. And the new job seeker doesn't have a relationship with the company, so he is just sending out email blind. Oh yea, I see recruiters from all over the country connecting with companies and trying to fill those positions. So it isn't even local anymore. Pretty much any shady recruiter can see an open position and try fill it. So the third-party recruiter has a gold mine on their hands. They upsell on finding good candidates because they are the only people that have the time/resources to actually do that kind of scanning. It is pretty shady but apparently lucrative. So the job seeker almost has to contact at least one recruiter. My question, what percentage of open jobs out there get filled by third-party recruiters?
