Interview
First round was an OA took it back in September didn't hear back until mid January that I was moved to the next round. Which was a technical hacker rank type question 2 question 1 leetcode easy 2nd was debugging and finally some simple conceptual questions with 2 current TDP Software Engineers went pretty smooth. They mentioned in the 2nd round I was supposed to receive a recruiter call before the second technical but I never got that so I went straight to the technical round. Next round was the final behavioral with the hiring manager just be prepared to answer questions using the STAR approach around 6 questions and follow up questions.
Interview questions [1]

LeetCode easy and a debugging for the technical be prepared.
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.
