They came to recruit on campus.

Talked to the rep and filled out a short application online.

Took a ~3hr programming/math test on campus, and was then flown up about a month later for on-site interviews.

Campus tour, software presentation, got to eat lunch at the very cool cafeteria.

Two interviews, one with a software developer and one with an HR person.

Everyone was very friendly. The software interview was not very technical; they asked me more about projects I had worked on and why I had made certain management/technical decisions.

The HR interview was a standard personality interview.

The programming/math test introduces a "made up" programming language and tests you on how it would work. Not terribly difficult, but definitely different than most technical interview questions (there were also some standard "write pseudocode/code to solve X" questions as well).
