I applied through a recruiter. The process took 1 week. I interviewed at US Air Force (Antioch, CA) in Jun 2011
Interview
There was no interview, you just take the ASVAB test and if you score high enough you can go for a tech job - but if you score too low you'll likely be placed in Security Forces (military police).
Interview questions [1]
Question 1
The ASVAB test was roughly 9th-10th grade math, english, and problem solving - with a few random tech and mechanical questions.
