AT&T TDP Intern interview questions

I applied on 10/21 for data analytics. I received a technical assessment on 11/19 to complete within 3 days. It was about 10 questions in pandas. I then received an invitation to a behavioral interview with a recruiter on 12/2. I interviewed on 12/17. I was asked two behavioral questions and then was told straightly after that I would advance to the next round. I formally got invitation for the technical interview on 1/4. I interviewed on 1/17 with two current TDP data analytics. They asked me some conceptual questions and live coding in pandas. I received rejection on 1/25.
