I applied through an employee referral. The process took 1 day. I interviewed at AT&T (Dallas, TX) in Aug 2014
Interview
Spoke with 2 people - an Executive Director and a Vice President. Both interviewed for the position. I had the benefit of knowing an internal employee that referred me, making the process and interview questions easy.
I applied through a recruiter. I interviewed at AT&T (Chicago, IL) in Jun 2012
Interview
Very professional process. One of the best experiences I have ever had with the selection process, very good HR and screening of candidates up front. Kept me informed along the way.
I applied in-person. The process took 3+ months. I interviewed at AT&T (Peoria, IL) in Apr 2012
Interview
We ask questions and then laugh in your face. We then make you do stupid exercises so we can laugh at you again. We tell you that you have the job and as soon as we open the door to let you out, we say, NO WAY will we give you a job.
