As someone in DevOps, the cool thing about the field is that people come from different skillsets. You can be a developer that works at a startup that needed to learn how to support your applications and become proficient in infrastructure and SRE. You can come from IT/Sys Admin and get teamed up with developers providing them Ci/CD pipelines and platforms. You can come from the Cloud world and expand your cloud skills into DevOps. Like being a developer, at the end of the day its solving problems and painpoints. Being on-call and waking up at 3AM because of an application going down, you learn and are motivated very quickly in figuring out how not to have that happen ever again.

Just curious, do you expect people from other background to have non-trivial knowledge of Linux admin? The problem is, for sure I can 1) study for a Linux exam or 2) setup a server in homelab, but for 1) most likely I'd forget about most of the knowledge in 1-6 months, and 2) most likely I don't need any advanced knowledge.

Does it eventually fall to whether I have the right connection? Anyway I'm trying to apply with some basic Linux knowledge (it's one of my daily OS), so far without any luck.

The hardest thing about developing linux skills is having consistent exposure. At a work setting its a lot easier because you are hosting applications that people will use. So people will notice if the application stops working, and its someone job to figure out why. The application might have crashed, the disk might be full, the network might be down. As you troubleshoot issues you gain experience and you remember more. The closest thing to at home is running something like a plex server or even your own ftp/dropbox clone. Something where other people will use it, which ofrces you to make sure its always running, needs to be updated because of OS updates or app updates, and possibly needing to expand it.
