That’s not too hard a question for me, I’ve been using the same DE for years: KDE

I truly wonder what’s the purpose of that behaviour though. Kill every last bit of motivation pre-job? I remember a time, when the hiring process wasn’t pure vitriol. Are these HR people so fed up with their jobs or what’s going on?

LineageOS has instructions for Windows/Mac/Linux: https://wiki.lineageos.org/adb_fastboot_guide

Same. The dev is very active and open to suggestions. I’ve been using it for a couple of months now and it’s working great.
