The interview process is straightforward. After applying online, I received an email updating me that I was moving forward in the process. Shortly after, I received a phone call from one of the Senior PM specialists, and they arranged a video interview via Webex with her and another manager. The interview was straightforward and nothing surprising, basic tell me about yourself, why AT&T, STAR questions. I would make sure you prepare your introduction, why AT&T, why should we hire you and quite a few STAR format questions with your examples relating to project management.
