US Postal Service Assistant Rural Carrier ARC interview questions

It was a group interview. There were a total of 10 people, including myself. Some were there for the RCA position as well.. We all sat in a room and watched a couple videos, then a couple guys came in explaining the duties and what to expect as an ARC and RCA. After that, we all got interviewed one on one.. Was asked two pages of questions... they were fairly easy. If you've had an interview before, they're basically the standard interview questions. In the email it said to expect to be there for a couple hours, but the whole thing lasted about 45 minutes. I believe if you were invited to the interview and you showed up, you pretty much got the job.. Not exactly sure though. Whole hiring process is done online, everything will be sent to your email. I applied 10/13/16, got an email on 10/18/16 for Motor Vehicle Record Search and filled that out, got invited to attend an interview on 10/24/16, got offered the job on 11/02/16, was also sent an email for a background and drug test.. Didn't get any further than that because I declined the offer. I'm sure it would've been a decent PT job, mainly just deliver Amazon packages on Sundays and holidays and occasionally run routes on Saturdays.. Just no benefits though.
