I applied through a staffing agency. The process took 1 day. I interviewed at NIH in May 2009
Interview
The interview process began with a pre-screening through the contracting agency/staffing agency. After the recruiter there interviewed me, I was interviewed by three managers employed by NIH. Several days after the interview the staffing agency contacted me to inform me they went with another individual.

I don't remember the questions. Overall there was nothing exceptionally difficult asked.
