AT&T a good place to be


I believe in AT&T and know they are at the edge of technology. The company believes in their people and offers all kinds of training to enable us to take on new jobs and to stay at the front of technology. The software defined network which we are building is the newest technology and AT&T has been involved since early 2000s. You have a great deal of autonomy at AT&T as long as you get the job done. You have the ability to do different jobs and to be challenged at all times.
