AT&T

Two telephone interviews followed by one in-person interview.

There were 4 rounds of interviews, taking about 3-4 weeks. First was the OA. Second, an HR call. Third, a Technical Interview. Fourth, Behavioral Questions. Each interview is about 30 minutes to 60 minutes long.

Pretty easy interview. They ask you about your college work and one coding question. They also like it when you talk about what AT&T is famous for or if you know something about their services.
