Can anyone give me some good information about mos 09s?

Hello, I'm 26 with 71 credit hours and have no unlawful tickets that will hinder joining the Kansas Army National Guard. What I'd like to ask is your personal experience joining O9s through the State option. I was told I would do BCT and then come back and drill with my guard unit until the summer OCS drills, will I be paid through BCT as an E3 and when will I be drilled through an interview to determine if I am Officer material, so you know I got what it takes but would just like to know what to expect. Appreciate you reading and comments. Thanks.
