I applied through a recruiter. The process took 6 months. I interviewed at US Air Force (Everett, WA) in Jan 2011
Interview
There is no interview. Go visit your local recruiter, be sure to educate yourself on what they can and can't promise you prior. They won't necessarily lie to get you in, but they have numbers and quotas to meet and at times they can fool you into thinking things that aren't true. Having information when you go in also shows them that you are serious about joining and therefor they will commit more time to you.

Question 1
