Pros
Exposure to networking, voice, and data center technologies. Great people to work with, but thats about it. Good place to get started and looks nice on paper but ultimately the experience is not worth it.
Cons
Zero culture. Everyone complains about how bad it is and are either actively pursuing new jobs or keep there heads down and accept their fate (which is sad). Too many mid-level and senior management around running an IT company like a sweat shop. Multiple mergers means everyone is on a different system in each department, database don't match up so customer information is either unavailable or difficult to locate. Management prefers to hire unqualified personnel to save a buck and views value on quantity over quality. Every engineer is a body in a seat and nothing more. Customers allowed to run rampant and make unrealistic demands. Where ITIL makes a Priority 1 incident a total network outage, some customers have P1s for a router down, while others view P1s and P2s as a 1 server with high CPU. Some customers have contracts where every issue they have will be regarded as nothing less than a P2 incident. No compensation for extra hours worked, or at best comp time is given, but because they are so short staffed one never has time to take vacation. With impending rumors of a buyout, management remains aloof and would rather spend money on flash for touring customers than hiring additional "Competent" engineers. Priorities are completely mixed and unrealistic with engineer on call expectations of 24/7. Voice and R/S engineers rotate on call every 3 weeks or less, and are expected to work 60+ hours with little pay increase or incentive. No culture or soul. VPs and Directors do not interact with their workforce, threaten to fire employees for mediocre and alienating reasons (managed services could be fired for simply walking through the Professional Services door.)
