US Postal Service CCA interview questions

I pretty much filled out an application than I recieved an email to do an online test. It is important you check your email frequently a two weeks after I got an email for my drug test and background. Than a month later I got an interview.You interview will be with other canidates in the room but it will be postmasters from different towns interviewing you. My interview went well. I got an offer letter and packet of paperwork in the mail that needed to be completed and sent back. Now im just waiting to get a call back with my start date.
