I applied through an employee referral. The process took 3 months. I interviewed at AT&T (Atlanta, GA) in Jan 2025
Interview
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.

Online Assessment with lc and a SQL question -> 3 part Technical (lc easy, debugging, basic oop questions and frameworks I like to use) to Behavioral (standard questions, focused heavily on teamwork and cooperation).
Got invitation to OA about a week after applying. 4 very easy questions, 2 math 1 programming 1 SQL. Received an invitation to schedule interview right after. Interview is with two current TDP members, and is technical, 1 coding question which was very easy, then they moved onto system design which I was not prepared for. Interviewers were nice and explained the process easily
