Jeez! If you're only thinking of joining the military because you can't afford an ATPL or you can't find a civvy flying job, then your interview won't last more than 5 minutes. You need to be a bit more dedicated, committed and motivated if you want to make it as a military pilot. If you just have it as a fallback option from the airlines then you're in for a rude awakening. Sorry to be blunt but that's the truth of it.
