None. Sign and go to boot camp. Then from there more training in your specific job field. If active duty you'll go to your duty station. Be there around 3 years and then move again
J'ai postulé en personne. Le processus a pris 1 semaine. J'ai passé un entretien chez US Army
Entretien
As the military is a voluntary commitment there is no real interview process. The only requirements are that you score the minimum on the ASVAB and can pass a drug screening and medical physical.
Go to MEPS and take ASVAP test. Then you choose your job based on your ASVAP score. If you have a good score, you will be able to pick any jobs. Please be prepared before you take ASVAP test and try to get a job that you really want.
