AT&T

Very good. They conduct different exams for selection, including medical, knowledge, and socioeconomic exams.

I was only passed through the first interview, but the interviewee was nice and explained everything well. Unfortunately, I was notified that I did not have the required skills for the job (probably because I hadn't graduated at that point in time).

I had an exam with six questions. I felt the exam was pretty fair, but I wasn't ready enough to do it and also felt really nervous, since it was my first exam.
