Talk to a recruiter . They will tell you what to do. Physical done at MEPS where they will go through everything. Do not lie to them even if recruiter tells you to
I applied through a recruiter. I interviewed at US Army
Interview
To be honest it wasnt an real like job interview.
Took an asvab test, filled out a lot of paperwork, took an physical training test and got height and weighed. I was sworn in like a month later.
