    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. The process took 2+ monthsinterviewed at ADTRAN.

    Interview Details

    Talked to them at a Career fair and had an interview with them the next day. They asked standard questions about my education and questions about what polymorphism is ect. Not a casual interview, but also not high stress.

    They invited me back for a second interview in Huntsville. This was an all day thing. It took about 6 hours of interviewing with a lot of different people. This interview was a lot more stressful. I was asked multiple times to do coding either on a white board or on paper. The questions are not easy, but they work with you to help you if you need it. Also, I lost some points because I didn't do a lot of research about the company and its competitors before, and they asked me about it. Have some technical examples to prove why they want you. They care more about your skills than anything else, and they do quiz you to see if they think you can cut it.

    Interview Questions
    • Bit coding for clock cycles, finding the 5 closest points to another point from a file of points, tell me about the research you have done on the company(competitors ect.), we noticed in the last interview you were lacking in (insert area here) what have you don't since then to rectify this if anything, how have your other interviews been going if you have had any   Answer Question
