A friend of mine interviewed this week. There have been no changes since at least last year (when I went through). The pool of questions has not changed, and they use multiple airports for the sim eval, but the profile and CRM process are unchanged.
One thing to keep in mind: they will try to tailor the questions to your particular background/experience. So, if you were a program manager, they will target the questions to that; if you spent a lot of time in the training department, you might get some questions addressing AQP; former chief pilots might get questions about disciplinary processes.
The interview is very straightforward, very relaxed, and may consist of as few as 6-8 questions. They give you a chance to explain any hiccups in your background, and understand that we all have at least part of a skeleton in our closet.
