I applied through a recruiter. The process took 4 weeks. I interviewed at US Army
Interview
Tell them the truth...they will investigate everything. If you lie, they will come down hard on you for it. If you are honest and straight with them you will have no issues. They will be all business and try to intimidate you. Stay calm, be polite and courteous but don't let them bully you.
Interview questions [1]
Question 1
Nothing they ask you should be difficult. If you don't know, just say so.
