I applied online. I interviewed at AT&T (Tel Aviv-Yafo) in Mar 2025
Interview
I received an invitation for AT&T Israel’s TDP online technical assessment via HackerRank. I had 4 business days to complete it, and once started it had a 3-hour time limit. The test supports Java/Python/JavaScript and expects basic REST/HTTP understanding alongside coding. The instructions were clear and the process felt structured.
Interview questions [1]
Question 1
One of the questions was a “Valid Parentheses / Balanced Brackets” style problem (stack-based).
I took a HackerRank exam that lasted around three hours. The questions were medium-level and similar to LeetCode-style problems. After completing the exam, I received a phone call from the recruiter inviting me to a technical interview.

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.
