Like when you send a .7z instead of a .zip or .rar to a friend or a teacher because that’s what your computer has installed and they’re like “Oh No, not one of those, now I have to install 7Zip” even though the same program that opens .rar also opens .7z I feel like people are way more annoyed when they receive a .7z
That’s what happens when you hire degrees and don’t test for experience. I’ve got friends going to school for compsci degrees getting primed for 6 figure careers jumping into my DMs to ask ME networking and programming questions. I never went to college and can’t even get an interview for entry level help desk.
