Pros
Good pay (average for call centers), relatively easy work, and the opportunity to not work in sales (a pro for a lot of people) is good. As long as you're not looking for a place/career to invest yourself in personally, this is a great place to work.
Cons
Management. Management. Management. The upper management seemingly have no idea what they are doing as most of the people they seem to promote lack your basic qualifications for the position. Also, any concerns that Agents (the grunts if you will) have are usually brushed aside, especially if those concerns are about the management itself. They preach openness, care, and transparency, but it's obviously a facade. For some though, this may not be relevant as it is a good place to work if you're just showing up for the check and don't care about your higher ups.
