A resume that documents 20 years of military service doesn’t really mean crap. There always needs to be some sort of sh** screen so that the organization is able to keep the most obvious weirdos/douchebags out.
The interview is not to validate your work history, it’s to validate whether you fit with the company culture and/or if you’re a nut. Not sure what the online tests actually do, they seem pretty stupid to me, but maybe the company thinks they assist in the validation process.
I’m also against any kind of flow that doesn’t include a sh** screen, for the same reason. Flying Delta pax around at a regional for 10 years says nothing about whether you’re an awful person to fly with or not.
Personally, Delta could have hired a few less O-6 Eagle types… but I guess the company likes them because they make great chief pilots though.
