I applied online and was contacted to do an interview via Montage. You record your answers to general questions (background, tell us about a time ____) and can rerecord an unlimited number of times. Then I was invited to an on-site interview day at their Louisville Headquarters. They spent a lot of time trying to convince us to work there and there were only two interviews, both relaxed and easy with no technical questions. They seem to have drastically cut back the number of interns in the program this year, however, so it was competitive.
