There is not a hiring team out there that even bats 90% let alone 99. The problem is that they significantly hinder their ability to get stuff done when they spend too much of their time in vetting/hiring mode. I've been there and it's no fun at all.
But this is required for the hiring staff to give the appearance of being important and needed within the company. If managers really understood how effectively non-management engineers can find and hire acceptable candidates when you remove the bullshit from the process, they would be confronted with the cognitive dissonance of their choice to staff up an army of HR and recruiters and talk all day about "ZOMG how hard it is to hire a good engineer!" and "look out for the toxic worker" and other such drivel.
