Phone interview and in person interview. The phone interview pretty general where they just went through my CV and explained the position to me. The in person interview was more technical, though parts of my CV/background were also discussed. The technical parts revolved around testing my familiarity with Unix and how I tackle various types of programming problems. All of the people I interviewed with seemed to be extremely helpful and pleasant-- even when I fumbled with stuff that's pretty basic. The process felt more collaborative than testing which I really liked, and afterwards I was given some very useful feedback.
