I worked at ADTRAN full-time (More than 10 years)
Great work environment
Great medical coverage through BCBS of Alabama
Huntsville has a very low cost of living compared to other high tech sites.
Great place if you like to innovate given their Hack-A-Thons and Innovation & Ivention weeks.
Good price on meals on campus
Below market salary for the given area.
I applied online. I interviewed at ADTRAN (Huntsville, AL).
Online application. Interviewed the following week with Human Resources. The group I would be working with. And then another round with HUman Resources. Overall the process was very quick, efficient, and friendly. I enjoyed my interview, but the job was not for me. Would apply again for a different position.
