There was no interview. Just look for a few emails and fill out the forms provided. After you fill out the forms, there will also be a background email you have to consent and wait for phone calls to do fingerprints.

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.
