Be honest with the recruiter and he will tell you when and what to lie about. The Air force is kicking people out right now so it might be harder to get in.
I applied through a recruiter. I interviewed at US Air Force (Cleveland, OH)
Interview
To join the Air Force go to a recruiter. He or she will talk to you and make sure you are eligible and then schedule you to take an aptitude test called the Armed Services Vocational Aptitude Battery or ASVAB. This test will help define your strengths and weaknesses and be used to determine your job placing. You can score low enough to be rejected so try hard and maybe even study. After you "pass" you are on your way. The time from be accepted to actually being sworn in varies for each person.

Question 1
Some questions will get personal. You must be honest. If you are not, you can forget serving in the military.
