I applied online. I interviewed at AT&T (Dallas, TX) in Oct 2025
Interview

I applied online. I interviewed at AT&T in Jan 2026
Interview
I took the OA in Oct 2025 and received no real communication until Jan 2026 where I was invited to do the technical interview. The interview itself wasn’t too bad: I interviewed with two current SWEs in the program, the live coding had a question that was a level of a leetcode easy, and it had an addition system design portion. I’m assuming I didn’t receive an offer since it’s been a few weeks with zero communication.
