Vantaggi
If you are starting your career this is a great place. DLT 101 is a fantastic program to give you the lay of the land. Also there are fringe benefits such as lots of food and activities outside work.
Svantaggi
Plantation system. Pay for employees who are actually making it happen is miniscule compared to what the managers are getting paid. It is actually disgraceful. Several people that leave are shocked at how much they were underpaid. To call the HR department very unprofessional is an understatement.. Some people are allowed to get away with everything while others are micromanaged to bits. And if you don't like to get hit on this isn't a good place to work. Additionally, as cloud technologies become more prevalent resellers are going to get squeezed out of the market so I am not sure this is going to be a great place for the future even if there were opportunities for vertical movement.
