I applied online. The process took 4 months. I interviewed at AT&T
Interview
Process was extremely unorganized. 1st round oa, heard back after 1 month for screening, did recruiter screen then it took month of following up to finally get invited to the technical screen that has live coding round and then oop questions. last interview is behavioral with director, director cancelled last minute. got rejected at end. I understand big companeis may have trouble managing so many applications but there was so much disrespect, disorganization and just flat out unprofessionalism in the process. This experience wasn't unique and when I tried to reach out to AT&T employees for interview advice all I got was "run"
Unprofessional. Interviewer kept delaying and rescheduling within the same day. I waited all day to interview. After that, the technical was kind of simple. Asked basic OOP questions and basic style leetcode. Also asked system-design related questions.
