All of those are just guesses, of course. My best advice is to seek some more personal advice locally; maybe show your resume to someone who has already gotten an IT job successfully.
EDIT: 1. and 2. should only apply to smaller employers; large companies will be more informed about that stuff.
Can you please look at me resume and give me some feedback drive.google.com/file/d/1dsIYNngdj...
