I had a Commercial AMEL CFI/CFII before even joining the guard but turned 30 during a stop loss deployment. Took the AFAST, but they wouldn't consider an age waiver, so no flight school for me. You may be in a different situation, but I'd be very careful before signing anything. I'd want a guaranteed slot in your shoes, and doubt that's something you'd be able to manage coming off the street. Not saying anything bad about any of it, but the recruiter's goals are much different from yours.
