The interview process is very physically demanding and makes you cry if you're a cry baby and you have to do like a lot of pushups in order to get the job.
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.
Show up to the recruiters office. Just score high enough on the ASVAB. Whatever MOS is available is what you can get. I would suggest fighting for the MOS you want even if you have to wait.
