The process is lengthy I applied on 08/05/15 and took test 473 which is fairly simple no real need to study for it. Then I did background and drug check. I got an interview in early September and all they said was they could only guarantee one day a week although its usually more and said we pretty much have the job there were 2 of us both dressed business casual. The post master didn't ask any questions other than do you still want the position after describing it in more detail. He said we would receive an email with a conditional offer which I didn't get until October 29th. Now I am just waiting for a start date I have accepted the offer.
