Interview was informal and no pressure. I was sent a automated email with my interview date and time but asked to contact the postmaster directly if I needed to change it. The interview was one on one with the postmaster of the office that I applied for. Prior to the interview there was an online exam that needed to me completed. The second step was to make an appointment to take an exam. Scheduling was easy and test results were made available online as soon as the exam was over. I then received an email to give permission for a DMV check and an email for the actual interview within 2 days of completing the exam.
