I've also written about the experience in that the "shops" divide the problem between client side and labor. The client side gets the experienced recruiter and the labor side gets the cold caller. This is not to say that all recruiters are bad but only the very small minority can close the sale.
Car salesman do not want to quote prices, interest rates, options, etc... they want you to come into the showroom where the music, smells etc are there to compromise your filters. Recruiters are no different.
By comparison I went to an executive recruiting agency in approximately 1990. That bar for performance and talent has not been seen since.
