US Postal Service Rca interview questions

I put an application in online with several post offices for the same position. After about two months, I got a phone call from a postmaster saying he wanted to interview. I went in to the interview that had a couple other applicants there. The postmaster didn't say a whole lot; just that there isn't any guarantee of hours. he walked us around the post office and showed us the vehicles. Finally after the tour, one person decided she didn't want to continue. I went into his office, answered his questions, and he said he'd pass my name onto upper management, who would then run my background check and decide if the should hire me. About a month later, I got another call from the post office asking me to come in that day to sign some paperwork. A couple of days later, I had to go in again THAT DAY to sign some more paperwork.
