AT&T interview questions

First applied back February 1, 2013. Received an email on February 7th that they would like me to move forward in the process and I then had to schedule to go and take the pre-qualification test. I tested on February 13th. I received the result of 'Qualified'. I didn't hear anything further until Monday, March 4th where I was scheduled for the Realistic Job Preview, which occurred on Thursday, March 7th. I was there with 3 other potential candidates. They take you through what the job entails, expectations, and such. Pretty good information. There were 4 managers present for the session. Then, you were broken off and each person went to a one-on-one with one of the managers. I was asked 3 questions. Seemed pretty straightforward and I did what I thought was fairly well, based upon the feedback from the interviewing manager. He also advised me, based upon my resume, on how to negotiate starting salary, which was a bit surprising. Anyways, today, March 8th, I received 2 emails stating that I did not pass on the one-on-one. Made a call or two trying to get some feedback, but needless to say, I was not hired on at this time.
