Really comprehensive interview process. Group-focused, but with one-on-one meetings with various executives. Just need to be comfortable speaking in front of small groups, sharing your ideas. At the end of the day, they just want to see that you can carry on conversations adeptly. They also take you to a restaurant "post-interview," but this is really just a better time for them to get to know you, and see how you converse with others. Be yourself but on good behavior.
