Intense, but quick. The recruiter was very efficient in moving forward to the next step. The interview panels were mostly friendly, except for 2 aggressive managers who weren't satisfied with any answers except what they had in mind. It was a tiring, 5 hour long process of meeting 8-9 people, individually or in panels of 2. It's often hard to say exactly what they want you to say, and they're looking for very specific check points.
