AT&T Business Analyst interview questions

I went in with a lot of confidence . But the moment i entered the person I had to meet was not taking my call. I informed the receptionist and waited patiently. Then after 20 minutes, some other person from the team comes in and asks for me. I was taken inside a conference room and asked to choose to sit wherever I liked. Everybody gave a handshake and smiled except for one analyst. The interview panel consisted of 3 project managers and 2 senior analyts. Out of the 5 people only 2 seemed interested and friendly. The other two did not bother to even ask questions or smile. The interview was over in 20 minutes even without asking me relevant questions. Every two minutes I was asked if I had any questions. Totally unprepared for the interview, the team conveyed a very unprofessional attitude. Be prepared to face a set of morons!
