Pros
The software are easy to understand. Raises were frequent if you had good performance, though at least for my position the cap was roughly $1.50/hr more than the starting pay. They had the option of private chats, which allowed employees to communicate with each other.
Cons
The operating system my project used was unattractive, limited, and had a tendency to freeze often. Ironically despite mainly dealing in customer service, their own service/support department was sub-par. The CD I needed to access the system got scratched; I called three different people to get an order made for a new one, and it took 5 days for me to find out that no one had done anything. My TL had to mail me one personally. In the meantime I had been logged in the attendance sheet as a no-show for those days despite everyone knowing what was going on. For my specific project, we had to keep track of every single time I logged in and logged out, whether for my break, end of shift, a tech issue, etc. It was useful if there was a problem with the computers, but on a regular day it was aggravating having to do that every day.
