"Casual" positions with the USPS are usually seasonal/temporary positions. Considering that it is so close to that time of the year in which they hire for the holiday season, I'm thinking you'll be hired as a Chrismas Casual. Which only typically lasts three weeks. There are some Casuals that get to stay on longer, but that's up to the supervisors. If they indeed are hiring you for the holiday season, you should get a letter for their interview process by mid-November. This process usually takes anywhere from 1 1/2 to 4 hours, depending on how many other people are in your group. Remember, this is only a temporary position. No benefits what so ever. And the rate of pay is generally $11.00/hour. If this were a career position, you must have first passed the postal Exam 473 and wait until they work their way down the registry to your score. It took over 2 1/2 years after I had passed the exam before I was hired for a career position. And, I scored in the nineties. From what I hear, the USPS is not currently hiring for many career positions. They're actually doing the opposite, by offering qualified employees the option to retire early. So being a Casual really isn't that bad. Good luck!
