The process can take a couple of months from rt to interview. But my whole process from applying to actually starting my training (I'm starting week 7 in Raleigh at the moment) took about 9months roughly.
I heard back the next day, which took me by surprise as i heard how slow they can be sometimes. The whole thing is a slow process. Put my application in, in August and got my start date for 1st of May so its about 9 months for the whole thing like Jamie said.
