The hiring process is a bit long (for me it took 3 months) so try to keep that in mind. With the interview try to be as confident as possible and stress your passion for sales (since AT&T is revolved around sales) and the importance of exceptional customer service. They utilize the STAR method for interviews as well so there aren't too many surprises. Good luck
I applied online. The process took 1 day. I interviewed at AT&T (Ponte da Barca) in Jul 2011
Interview
Received a call for a position for AT&T. had a phone interview and then a skype interview with the manager since I was at home and she was in Brno.
