The money is nice, and it is a "Sales" job, but their is some creativity to it. You are trying to marry a candidate to a client. They are both moving targets. Its a skill game, more than a "bang the phones" game that a normal sales job is.

There are a number of quants and C++ developers who made the move to recruiting, sometimes after talking to a recruiter and realizing that there is money to be made (usually more than they are making). I related to this: I did a lot of IT and web development work in my youth, and that always entailed being someone's bitch and not getting recognized for the work I did (Only the mess ups get noticed: Like being a goalie in soccer). In recruiting, you see the angles, work your relationships and make money. Its a one person job (mostly) and there is a lot of enjoyment in that aspect. At the end of the day you say "I did X placements, billed Y amount. Thats what I did", which isn't about the money as much as its about having a quantitative score that demonstrates your productivity.
