The process was very formalized. I came in for several case interviews that they seemed to make more difficult than need be. It was as if they were trying to trick me, but in odd ways. If I started moving down the wrong path, they would encourage me and be supportive. Likewise, when I was on the right track, they pointed me in another direction. All in all, it was ood. People were sort of friendly, with a little coldness. Not sure if that was intentional or not.
