No interview was conducted for the job. They just look at your application materials. No need to prepare anything. They will request you traind for the LLV mail truck though.

Application process is fairly straightforward. Apply, then take an online test that filters out potential personality conflicts. The actually interview with the whichever office is one's home office was also straightforward, important question being time management for a carrier that needs to meet a deadline. Most questions were already asked in the online test so the in-person interview felt more like a chance to give the manager an opportunity to get a read on someone to potentially catch something an impersonal test would miss.
