I don’t see anything wrong with using more than one agency. I got my current job through a head hunter, and at the time I had 3 agencies trying to find me positions at the same time. It may work differently in other fields (I’m in IT) but they all found my resume on Monster, and knew of an unpublished position that they thought I would fit. Then I went through an interview process with each headhunter (so they would better know my interests and qualifications). If I said I’d be interested in the vague position, they’d tell me who it was and what the position was exactly, and submit my resume to the company.
So at this point, I know that I’ve been submitted to Acme Consulting or whatever. If I got to this stage with another headhunter and it turned out to be the same position, I could say that headhunter 1 had already submitted me. This never happened to me, I’m guessing because a company would only go with one placement firm at a time, to reduce the chance of getting the same candidate from 2 people.
It makes total sense to me that a company would not want to be placed in the position of having to decide which headhunter gets the finder’s fee. I forget the number, but the fee is generally a good chunk of the candidate’s yearly salary. This is generally acceptable, because you can spend a lot of money internally on recruiting if you have to do the pre-screening yourself. The tiny company I work for only has 1 HR person - this could double or triple if they put up a listing on Monster and had to screen hundreds of eager applicants.
So this is probably an agreed-upon practice. Companies will reject you if you’ve been reffered two or more times to avoid the hassle of multiple placement firms claiming the finder’s fee, and headhunters will work hard to make sure that you haven’t been submitted to the position already, since that’d just be a waste of their time.
I kind of like headhunters, as long as they’re professional (there are some really shady places, though). At the time I was looking, I was working 50+ hours a week, plus travelling, and I would have gone nuts if I had to troll though listings at the same time. I really like my current company, so it worked out well.
Voyager, all of the headhunters knew that I had other people looking for me, and didn’t seem to think it strange.
archmichael, at the point you’re talking about (applying for a vague posting), you’re several steps away from actually having your resume submitted. If a placement firm does submit your resume without telling you exactly what it is, they really, really suck. Even the one really shady place I dealt with for awhile told me what the post was before they submitted me.
