serious recruiters that know what they are doing.
I have worked with several staffing agencies over the last few years and these guys are VERY different. They don't waste your time, they respond to all inquiries and although you may not like what they have to tell you, they are always up front and "real." They placed me in several long term contract positions at a rate FAR and ABOVE what other agencies in the Atlanta area were paying.
I had a friend who had a misunderstanding with one of the recruiters and the Managing Partner at Execusource immediately called them to rectify the situation, something that is un-heard of in this industry!
