Would you be able to offer some examples?

I don't know what the deal is with some recruiters--I mean, in general. I attended a recruiting event from the US gov near graduation, approached one booth and introduced myself. A friend came over and inquired about a job to which she said "oh, well that's for the creme de la creme" and turned away without asking him anything about himself!? I found that incredibly rude.

Geeze, I wish I had her psychic powers /s.

Personally I think it has to do with the problems of giving people power and authority over others...
