Cons: work hours.
the company itself is great to work for, the co-workers are awesome.
Management is VERY approachable - some of the most approachable people I've ever met work there. I can't say enough good about the people to give them justice.
BUT - the hours you work aren't so great. If you honestly don't care what time of day you work, or what days off you have, working holidays, and are very, very flexible to trade with anyone at any time, you'll probably really enjoy it there.
I found it hard to have a life outside of work if you don't switch departments immediately. If you have outside of work commitments, it can be quite difficult to find a work-life balance. If you are on a flex schedule, your schedule can change at the drop of a hat (more and less hours and shift time changes)
if you are on the picked-schedule, your hours are pretty much set but it is very difficult to get a desired shift and days off. There is little turn-around there so you will catch yourself on the night shift (working weekends) for a long time. (there are more late shift spots than there are people who want to work them and seek them out, so don't let that statement mislead you)
Advancement is slow, but they'll showcase fast ladder climbers.
I really enjoyed working there - though it is typical call center work with the same statistical requirements as any other call center - talk time, revenue and booking percentages.
