AT&T Software Engineer(Internship) interview questions

First I took a very simple technical assessment online. Afterwards, they contacted me and wanted to set up a 30 minute behavioral phone interview. I was then setup with a 2 hour Skype interview, where the first hour was a behavioral interview, and the second was a technical interview. Did well and the interviewers told me they liked me and gave me good marks, but I was rejected a few days after the technical interview. I believe that if I were to move on, there would have been one final phone interview with the hiring manager.
