I applied online. The process took 4 weeks. I interviewed at AT&T in Jan 2015
Interview
Timely- I applied and was contacted 2 weeks later for first interview. The first interview was 45 minutes and second interview 30 minutes. I spoke with a manager and various members of his team. They were polite and excited to speak about their company. Questions were generic and not position specific- which was weird. The team was open to answering questions from me and they were very professional. I was told I'd hear in one week, but its been a month and I never heard anything. It is annoying to go through the interview process and never get so much as an emailed rejection. Other than that, good experience.
Interviewed with several people on team and in chain of command, including boss, boss' boss, team members/peers, etc. went back for several interviews. met with human resources dept. took management test.
