    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.

    Application Details

    I applied through college or university. The process took 3 weeksinterviewed at ADTRAN in September 2014.

    Interview Details

    Was first recruited at my University, and had a short interview. Few technical questions were asked at this point, and I was invited to interview in Huntsville in a few weeks. The onsite interview was a long day. I had 9 interviews, all with different departments. There were a few technical questions, but they were fairly basic. I asked a lot of questions about what each group did, but by the end of the day it all started to run together. Each interview was different. Some were with a single manager, but most were with a manager and a few of their engineers. The campus was very beautiful, and I got the impression that this is a very team-based workplace.
