Most of the people are really great to work with.
If you are a CSR or TSR you will have a lot of time in between calls unless you work mornings.
Management has a hands off approach but is approachable and friendly when needed.
Will expose you to some internetwork issues if you are wanting to get into that.
Cons
Phone work is phone work. Many clients do not have any idea what is going on...AT ALL. If you are not very customer service focused or are easily stressed by misinformation and confused customers this job is not for you.
Pay is just OK.
Very strict attendance policy. A few minutes late is always late.
A lot of lack of information....but it is constantly improving. They simply handle a lot of other ISP clients with different systems and different levels of disclosure. It can be daunting, but they do a good job all considered.
Sometimes it's not busy enough. Bring a book. Someetings it's very busy.
