I applied online. The process took 4 weeks. I interviewed at AT&T (Atlanta, GA) in Feb 2025
Interview
Took OA and passed screening. Moving on to the technical interview. Any advice on what to study up on? I've heard OOP principles and leetcode easy are on there. So far the interview process has been really smooth and professional.

Question 1
When was a time when you had to talk in front of people without preparation?
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.
