Pros
There are some excellent opportunities to work on new technologies and services in the wireless industry, if you're lucky enough to be in a group assigned to work on them, and have leadership that trusts and empowers their staff to complete the programs. AT&T is trying to stay at the forefront of communications technology by pursuing new products and services, and creating labs and partnerships to encourage innovation among startups and developers.
Cons
The concept of "One AT&T" hasn't really permeated throughout all of the groups. There is still a lot of distrust and competition between marketing, engineering and operations teams. Bureaucracy and inflexibility of policies stifle a lot of otherwise positive energy and initiatives. Career development and advancement are a complete joke. Unless you've got a senior exec mentoring you and helping to get you visibility for promotions, there are no ways to be promoted except to move to a different job at a higher level. Staff at higher management levels like Executive Director, VP and Sr. VP are shuffled around between groups or rearranged in periodic reorganizations, despite job performance or staff morale issues, at the cost of little to no opportunity for directors and other high performing staff to be promoted. Staff morale has been declining for years, due to the lack of opportunities and the constantly shifting strategic initiatives that never quite seem to achieve what's necessary to effectively compete with Verizon.
