Multiple day process. With different people. One of the more challenging processes I've been through. I felt, they were very reserved in letting a candidate know what the next step is, because a percentage don't make it past the first interview.

Two Phone Interviews. Very nice people. I didn't wind up going with the job, and they were very understanding. Interview was pretty usual. Name a time when you had a difficulty and how you overcame that difficulty kind of thing.
