I worked at US Department of Commerce full-time
smart and hard working colleagues
projects can be slow and bureaucratic
A 30 minute phone interview started with behavioral questions then moved on to specifics of the position. Applying for an internship related to East Asia, I was asked about recent developments in the region. It was very straight forward, and if you are interested in the area in which you are applying (which is reasonable to expect), any questions should be relatively easy to answer.
