You think Chinese students are "honest and good"? That really makes me laugh! Many of them are liars and cheats! As the OP said, yes, recruiters are shit, that's all there is to it!

Even you blokes who spend years spouting on about their evil suddenly go and use a recruiter-one of your very own has come a cropper recently as you well know. The recruiter is not the problem ,SB, it is failure by the FT to check out the company that he ends up working for.
