No interview process. Up sign a contract and go to basic training. Once you’re done with that, you get stationed at a base to do your job. The only thing is that you sign a contract for at least 4 years depending on if your want to be active duty or reserve.
Very straight forward experience with huge number of questions in order to gain all relevant information needed for enlistment. The application and interview process can be done in a single day, if all documentation is ready to go and you are ready to commit.
No interview, more concerned if I could pass a PT test. I also took the ASVAB. Adding even more words because I have to have 30 words for this to accept my review.
