I contacted on LinkedIn by a recruiter, who I saw there were mutual acquaintances with and she even was my dads recruiter for a while. She did her work and now gets a percentage of my salary. That was an arrangement between her and my company, so I never paid her personally. The fact that she negotiated my salary up by 10k and the opportunities she made possible makes it a win win in my eyes. In other words, I don't think them being paid by their recruiting company makes it a conflict of interest. In fact, this gives them an incentive to negotiate the highest salary for you.
