    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.
