Depends....most help desk are call centers and not onsite (hands-on)
Call-centers can improve your softskills. You'll need to really brush up on your softskills as all call centers base your performance on customer satisfactions. (technical skills is somewhat secondary...)
I'm working at a call center now. As i see it, the future is not that bright.
The next big step up is to go into management.
but if your just starting to join the work force...I would say that it is not such a bad start (pay is always a big incentive...)
Good Luck
