AT&T interview questions

Interview was 1:1 initially but due to weather conditions it got converted into a telephonic interview. The questions that I was asked was very general, nothing specific to the job or domain. I just had a conversation with the interviewer. I was not given specific job description. The interviewer finally told me that he would contact me after 2 weeks

Very friendly and the entire interview was by a group (so no one on one). Each member of the team had questions prepared for me. They asked about my experiences but I distinctly remember being asked about something I did a long time ago that wasn't even on my resume. Apparently they looked me up and found somewhere that I had published a poster and asked me detailed questions about the research.
