AT&T Management interview questions

The AT&T company has been the home of job ever since graduating from Engineering School with a MS in Mechanical Engineering. I recieved a call asking about an interview for a "High-Management" Position at one of the AT&T Call-Center. They were offering me $95,000+ (USD). They asked me multiple questions about my under-grad degree as well as my graduate degree. They also implied that if I wanted a bigger, more innovative job, (working at the AT&T tower in Downtown Atlanta) They would like to see me go back to school for an MBA.
