I have been working at US Army Corps of Engineers full-time
USACE is certainly a team of teams. Everyone works together on a daily basis to engineer solutions to complex problems.
USACE is a process-driven organization, and as part of the federal government can be overly bureaucratic.
I applied online. The process took 3+ months. I interviewed at US Army Corps of Engineers (Reed, KY) in April 2018.
The interview was pretty cut and dry. Nothing that seemed out of place at all. Alot of questions abut past work history, safety (which was a big one), ability to work outdoors and all shifts. A good experience overall.
