They flew me to their headquarters in Dallas and housed us in the Adolphus which is a very nice hotel. they took us out to dinner and drinks the night before the interview. By "us" I mean the other candidates who you will compete with. The interview lasted from 8 AM - 4 PM. The first few hours were spent getting familiar with their software. From there you will encounter roughly 5-6 interviews, each lasting about 30 minutes. They will feed you lunch in between the interviewing sessions. There is one programming section which is easy. they may or may not ask you to solve logic puzzles. Know your Java or C# syntax. they will give you a laptop to write your code, however they will restrict you from accessing documentation. Interview was easy but I fumbled because it was my first interview.
