There was no real interview process. You are either qualified to serve, or you are not. There are standard stipulations that must be met like any other job. You must be able to pass the drug screening and criminal background check.
I applied in-person. I interviewed at US Army (Detroit, MI) in Nov 2013
Interview
Took the oath to serve. IF you have no criminal record and you are always trying to better your self you will do fine. its less an interview more a hunt . words
I applied through a recruiter. I interviewed at US Army
Interview
They ran a back ground check, and took a physical fitness test to make sure I met the minimum standards for the army. After that we reviewed my scores from the ASVAB and the recruiter said based upon my score I am qualified for every job in the army.
