US Postal Service Assistant Mail Handler interview questions

I got an email with a date of the interview, and a number that i can call and reschedule if i couldn't make it that day. Called the number, and they told me they can't reschedule it, so I had to change my plans in order to go to the interview. When I got there I was expecting a lot of questions, but instead signed bunch of papers, and got a tour of the place. They tell you about the job, and ask you if you are willing to do these things, and hire you if you pass the drug test. p.s. My interview was with the postmaster.
