Empathy is like sharing an experience.
Alice is holding a stack of papers, they get a papercut and react (yelp, pull their hand back, maybe suck on the injury). Bob sees Alice’s experience and may remember when they had gotten a papercut before or just imagine what that experience is like, and will share in the same feelings (or how Bob would imagine Alice is feeling, anyway). Bob may yelp too, or fidget with their own (uninjured) finger.
Apply and see. Worst case is you learn something.
My interviews for linux-related roles were basically, “how do you change directories? What does ls do? How do you edit a file?” (Last one was trickily open-ended to also see what my preferred editor is). I’m not even sure they asked where log files are typically stored.
As for what to put on a resume, just say that you run a home lab or something.
