It was extremely behavior and core values focussed. They were more concerned with asking questions about how you have reacted to situations than what you would do. They ask for examples. They also value a finding the right people than all the correct experiences. Much of the leadership have read first Break All the Rules and Good to Great. I would google those books if you are not aware of the content before interviewing. I wouldn't quote the book just understand what they value as an organization.
