There are some skywest captains that provide interview prep the day before your interview. They have most of the questions for the written test which is a pain in the A$$. It is stuff that you probably never have seen or don't remember, but the average score is high 50's-60's. They also have a sim that they can give you a mock sim ride practice. It's usually exactly what your going to do in the interview. as far as equipment it looks like a lot of new hires will be going to the 175's since there are only 40 FO's that bid for it.
