There are 2 types of recruiters, those with "skin in the game" (like in house recruiters) and those only trying to make their quota so they can keep eating.
There are 2 types of candidates, those who need a job bad enough to work with any recruiter, and those that can get a job easily because they have "in demand" skills, they don't need (or want to deal with) the second type of recruiter.
Luckily, I'm the second type of candidate and I will never again deal with the second type of recruiter. I love captive recruiters, even if I don't particularly care to work for their company, and I will happily give them referrals if I can. But the independent recruiters are all scum, and I choose that characterization carefully, I've never met one that was not, though interestingly they all swear they are different than the others. I'm working on a form letter to send to the scum recruiters, but I'm too nice to actually send it, so I'll just continue to ignore them. Like telemarketers and spammers, I realize they need to make a living, they just aren't going to get any help from me.
