US Postal Service interview questions

The hiring process went a lot faster than expected. I applied online and had to take a civil service exam before I would be considered for the position. I passed the test with flying colors and a couple weeks later I was called to set up an in person interview. After the fairly informal interview process during which the manager was already speaking as if I already had the position I was told it would be around 3 weeks before I would hear back from their central office as to whether I was selected. Apparently the manager you interview with only makes a hiring recommendation and then the central office makes the final decision. It was only about a week and a half and I received a call that they were offering me the position.
