I applied in-person. I interviewed at Royal Australian Air Force (Perth, Western Australia) in Jun 2014
Interview
There was no interview process when applying for a Defense job.
I went in to Defense Recruiting and they asked for my name and details.
They told me my name was put in a pool and then they'd get back to me.
It took about four to six weeks.
