Job preference change after CFAT??

[Kris Ackerman]

Hi Guys, I recently did and past my CFAT, and the recruiter ask me the 3 jobs I want to do in the military, I choose cook or Tank crewman, and gunner. But If I change my mind and want to do other trade. So, at what application processing point that the job I choose will be finalized , is it before or after the interview or after BMQ?
