Vantaggi
For the majority of departments, it is a decent employer for someone fresh out of college but don't stay longer than 2-3 years or your career will suffer due to a plateau of transferable skills. If you are capable and experienced (solid skills, innovative, creative) it isn't worth staying longer than 2-3 years because you will loose momentum in the work force. Advancement opportunities are few and far between and pay increase is slight if at all.
Svantaggi
Many poor business practices used that are not transferable. There is an "in crowd" and if you are not part of it don't stay longer than 2-3 years or you will be cheating your potential. My career path was delayed due to false promises and constant re-organizations of the various leaders and departments; I stayed too long (6.5yrs) which was a huge career delaying mistake myself and former colleagues also experienced.
