What I find appalling is the overwhelming ignorance of most so called technical recruiters. I've dealt with over 25 recruiters so far and I don't think a single one could tell me the difference between a systems administrator and a network administrator. How does the slashdot community see the difference between a network and systems administrator? In my own opinion a network administrator works with Layers 1-3 of the OSI Model and a system administrator works with Layers 4-7 with some Layer 3/4 overlap in both positions. How do you deal with recruiters and human resources people that don't know the difference? Educate them? Politely ignore them? Tell them to stop wasting your time?
