I applied through college or university. The process took 1 day. I interviewed at Institute for Defense Analyses (Alexandria, VA) in Mar 2010
Interview
The hiring process was much like most typical internship processes - throw your resume, cover letter, and transcript into a black hole and hope to hear back. Luckily for me I did hear back. The interview was about half an hour to forty five minutes and the PhD's interviewing me were very nice (seems like they're more brutal with Research Staff Member and Research Assistant candidates than Intern candidates). Week or two later I got the offer.

Interview
Applied for a PhD statistics internship based on the advertisement in Amstat News. They contacted me to setup a phone interview. Two statisticians interviewed me. No technical questions, just asked me some standard questions: Why I wanted to join, what was my research on, etc. Overall a very friendly conversation
