    I worked at ADTRAN full-time


    Decent compensation package, and plenty of "doers" that make things happen. The hardware engineering team produces quality products at competitive price points.


    The Enterprise division is micro-managed to the point that director-level employees don't have the authority to make decisions and spend capital to invest in the future of the company. Although products tend to perform well, the company is generally not innovative and tends to implement features only after they've been proven in the market.

    Advice to ManagementAdvice

    Give your senior employees more decision making authority, but don't be afraid to shake things up if they're not performing or are incapable of making (good) decisions.

    Neutral Outlook

    Anonymous Employee in Huntsville, AL (US)
    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
