I applied online. The process took 6 weeks. I interviewed at US Army (Columbia, SC) in July 2013
Interview
A panel of three, two in-person and the third by video teleconference. They rotated asking questions. Very few of the questions actually had to do with the specific job and more with activities of the organization at the higher levels.
Interview questions [1]
Question 1
They asked me to provide a copy of my military officer (Reserve Officer) evaluations for a civilian Civil Service position.
