Very different than what I expected. I had been prepped/warned that it was a grueling interview process and the interviewers would tear me to shreds. It was not at all like that, it was very conversational and light. That said, my experience was atypical, I think. I did not meet with too many people, and didn't have the group debate interview, or even a phone screen initially. I was brought right in house. I had two in house interviews, and the second actually included me attending a team meeting which was interesting. They will have you take several personality tests before coming in house, and the results are taken very seriously and used a lot throughout the hiring process.
