I actually took the test three years before the interview. The test is more than four hours long and is a personality test, skills test, IQ, etc..Then you wait, and wait, and wait. They will send you your test score and you have to be over 80%, I think, to even be looked at. After that, if they get down to your name in the test score rankings, you will be called in for an interview. They don't really tell you much about the position, normally they say there are a few spots they are trying to fill. Maybe a few months later you will get a letter saying you have to go for a drug test and that they are offering you the job if you pass the drug and background check. Even after accepting the job, you have to train and then take more test--and if you don't pass, you're terminated. Lets say you get the job...then you find out that you're going to doing, xyz--but it's on a part-time basis, no regular hours, but the hourly rate is great. So you accept and then you learn they own you. they send you where ever when ever and if you only get two hours of scheduled work for that week, you have to run around and try to pick up hours at other offices just so you can pay the insurance costs. The last portion is the stuff they don't tell you in the interview.

The United States Postal Service typically does not conduct formal job interviews. Instead, applicants are evaluated based on online assessments, background checks, and meeting job eligibility and qualification requirements. You only need to apply.
