I applied online. The process took 1 week. I interviewed at AT&T (Orlando, FL) in Apr 2015
Interview
It's just like how other's have posted here. It didn't take up full one hour. Studying the questions that's listed on the website helps a lot, but also asked couple of generic questions like why did you choose AT&T, and what do you know about the program. So make sure you're prepared for both the behavioral and questions like those.

Question 1
Tell me about a time when you were most proud of.
Why did you choose your school?
The interview wasn't too bad, and there were multiply interviews with recruiter and then management. The process was seem less as they would update you through email. Overall good experience but the program was very cut throat. sink or swim.
I applied online. The process took 4 weeks. I interviewed at AT&T
Interview
Applied online and heard back a couple weeks later about taking a behavioral quiz. It was 88 questions long and was pretty simple. I was then had a skype interview which was pretty simple with mostly behavioral questions. Interviewer seemed kind of uninterested but was nice enough. I recieved an email saying I was no longer being considered around a week later.
