Someone who will get you a job. Rather than getting you the job you actually want, they'll often try and recruit you as a
recruitment consultant, recruiting
recruitment consultants.
A cunning way to slip an infinite number of middlemorons into the revenue stream.
Eventually there'll be only two people left doing any actual work, while the consultancies (sp?)spend their time poaching recruitment consultants from each other. Big signing-up bonuses all-round lads, eh?
