In addition to aviationinterview.com you can ask your recruiter for a interview prep where you can do a skype interview with a interviewer (usually a skywest CPT) and they will tell you how they conduct their interviews, what questions they ask, and what areas people seem to be weak in.
Also you can go to their orientation before you get hired, and they pay to fly out out to salt lake and you tour their headquarters and get alot of questions answered and they go over some interview questions if time permits.
These resources are available to anyone, not just RTP.
