US Postal Service Rural Carrier Associate interview questions

I applied online for the position. After passing an online exam, I scheduled myself to take the 473 exam. My combined exam score was over an 84. I waited for about a month before I was contacted for an interview. The interview was done in a group. They first gave us a tour of the post office and explained the duties of the job. They then interviewed us one-on-one in order of our test scores with the highest scoring going first (I was the second person they interviewed). They asked standard interview questions. I was then called a couple weeks later and told they had two openings and was asked if I was still interested. I said yes. They emailed me paperwork so they could conduct a background check and drug test. And, that's as far as I have gotten in the hiring process.

I have not had my interview yet it is tomorrow 2/23/2015.The process up to this point as been very fast I filled out an application on 2/1/15 where I scheduled an exam date of 2/5/2015. I went and took my test and had my results emailed to me within a few minutes of taking the exam I scored 83 not sure how well that is.I got a call for an interview on Friday 2/20/15.So i will let everyone know how it goes.
