More than anything hey just want to get to know you. They will ask you about your background and various experiences in the Airlines. They'll probably ask you why spirit and why you want to leave your current job. If they sense that you see your current job as a stepping stone they'll probably not hire you, and the same goes for they way you view spirit. They are mostly looking for guys who could be happy here or even staying where you're at. It's a stress free interview, and the stuff on aviationinterviews.com is a good sample of what you can expect. Good luck
