Interview took about an hour. I did not interview with the post master.Though I suspect they were high in management. I was interviewed at the main post office in Colorado Springs. I did not get asked a lot of questions about my work experience. Which lets me know they have a high turnover rate. I was basically told about what the job involves, though they did not do it anywhere near enough justice. Due to my high post office test score and prior military service, I was offered the job on the spot.
