Application
I applied through other source. The process took 2 weeks. I interviewed at Army National Guard (Dallas, TX) in Aug 2022
Interview
The interview process is very easy. So long as you are passionate to lead, care for your subordinates, and have some insight on what your role will entail you will fare well during the interview and thereafter.
I talked to the OSM over the phone, he is the officer state manager for the state to which I was coming for my next college, and sorted out the details of eligibility for being in the guard at the state. He offered me different branches, such as engineering, military police and field artillery. There is also aviation but that is a harder process where you need to go to flight school.
