I’ve Worked with Hundreds of Recruiters - Here's What I Learned

This much is true: Recruiters make the hiring market go round. They trade in human capital. If you’re pissed at your boss or you feel under-compensated, a recruiter is a godsend. Same if you’re unemployed. And if you’re a hiring manager looking down the barrel of onboarding 1,000 new customers in the next six months, the recruiter who can help you get the 20 CS reps you need will become your best friend.
“If you think Facebook, Google and Twitter were built without recruiters, you're deluding yourself.”

All three of those companies needed dozens of people dedicated to hunting down the best people possible to write code, close customers and keep them happy after the fact. It’s the best practice that no one wants to talk about.
