    I have been working at ADTRAN full-time (more than 8 years)


    Laid back atmosphere. Almost too laid back. Get the job done and you may never see your boss. Technically challenging. Always something new to work on. Open door policy so you can get information from just about anyone about anything.


    Get the job done and you may never see your boss. I did list this as a pro, but it can be a negative. I've been here 7 years and talked with my manager about 10 times. Talked to my boss's boss about twice. No movement. It will take 15 years and everyone in your group to leave before you are promoted.

    Advice to ManagementAdvice

    Move your engineers around or they will leave. Its not about the money, its about keeping the minds working. Working on different projects. The ones that know the job, promote.

    Application Details

    I applied through college or university – interviewed at ADTRAN.

    Interview Details

    College student interviewing for entry-level position. 8 hour interview process, cycled through about 10 different groups/managers. Each interview was different in terms of length (20 min - 1 hr), number of interviewers (1 - 7), type of questions, etc. Some focused solely on soft skills, some solely on technical questions, some were a mix. No breaks except for lunch which was also an interview.
