unix admin incident levels

[Vasadi I. Claudiu Florin]

Hello,

This is probably not the best place for this type of question, but here  
goes anyway:

"Senior Network & Unix/Linux Administrator Lever 3/4 incidents"

Now, that level thinghy I was unable to find on the web what exactly it  
means. I mean is level 4 the worst or the easyest ? Or maybe that  
easy/worst terminology isn't quite the best used.


Gimme a hint pls.
