Pros
If you are not particularly ambitious, AT&T may work perfectly for you. AT&T has incredibly low expectations of it's employees except that adherence to bureaucratic rules and regulations is to trump everything, including the most blatantly obvious good ideas. Likewise, the low expectations can be taken advantage of in terms of the overall time commitment required for the job, to the extent that competent and capable people can meet the low expectation with minimal effort and time.
Cons
AT&T is a toxic work environment, especially in terms of Information Technology. The company does not understand the necessity of investment in technology, people, or facilities and would generally rather legislate and regulate than innovate. Ironically of course, the end result of this approach is that implementations end up costing significantly more, value-add is significantly less, and everyone involved from customers to employees is significantly dissatisfied.
