Vantaggi
This is a very Big company with a variety of work opportunities, and geographic locations. Experience at at&t looks good on a resume. It is a stepping stone to other employment. The company provides decent training opportunities. If you can find a good group, then you job satisfaction can be high, although, finding a team with good leadership, is difficult. Work can be satisfying, but again, you have to search to find a team that has good leadership, and can challenge you with work and at the right pace. Often inexperienced employees get stuck with work assignments that are too complex which is better than too boring.
Svantaggi
There are no promotions in middle management or very few. There is no supervisor/management empowerment. AT&T leadership tends to be at 30,000 feet. Those close to work see management's numerous mistakes and even huge errors. The processes are nothing short of horrible, too much time to do anything because of trying to make single processes work for all groups and situations. Levels of approvals needed for even simple decisions go way too high. People often give up trying to actually be innovative, or to do the right thing since it usually becomes a battle against leadership and process. This poor senior management philosophy is causing many good new employees to leave as well as very talented experienced employees taking early retirements to work elsewhere.
