I applied online. The process took 4 weeks. I interviewed at AT&T (Atlanta, GA) in Feb 2014
Interview
I got a prescreening skype interview which lasted about 20 minutes, and then about 7 days later they contacted me asking to schedule a technical/behavioral interview. That lasted for about an hour and then literally hours after the interview I got scheduled a final interview to speak with the director of the program, and a day after the final interview, I received a job offer.
