I applied online. I interviewed at US Postal Service in Oct 2019
Interview
It was very quick. I heard back very soon after I applied for an interview request, the date, and time. I did have to wait awhile for the interview, but the interviewer was friendly, and it was a nice process.
Group Interview, they check Drivers License and other paper work asked a few questions about fitness and schedule and state they will recommend you. Nothing fancy at all. Customer service questions asked your more so basically hired if you make it to the group interview.
Very easy, met with local Postmaster and was explained the job duties. No pressure interview. I was given a brief tour of the office and introduced to several employees. Positive experience.
