AT&T interview questions

I applied online and recieved a call from HR within a week. The college recruiter was a nice lady from Florida, she called on a tuesday and scheduled a webcam interview on friday; she will send a link which allows you to download the AT&T webcam connect. She is very polite, friendly, and makes you feel very comfortable during the interview. I actually thought I was doing very well because she would respond to some of my interview answers, for example, when she asked about a weakness after I explained my answer in detail she told me a story about when she had to interview 500 people. The interview took 30 mintues and after the interview I was allowed to asked questions. I asked about the day-to-day responsibilitites and the next step in the hiring process; I felt like I should of asked more questions. She told me I would hear back from her on Tuesday. I felt very confident about the interview, but on tuesday morning I received a email explaining I didn't meet all of the required criteria for the position. None of the questions were difficult.
