Just walk in and show up. USPS not what it used to be

The interview process at the USPS typically includes a written exam, an in-person interview, and possibly a background check and drug test. It's important to demonstrate strong communication skills and a customer-focused attitude during the interview. For more insights, consider reaching out to current or former employees on Jobcase or consulting resources on other job search platforms like Indeed or Glassdoor. Good luck!
