How much do you know until you got this!

So I have been learning Linux by purchasing some tutorial videos from Udemy, and watching lots of Linux tutorial videos from YouTube as well since education seem free this time. I wonder how much knowledge we should know in order to be able to get a job there? and perhaps, everybody want to share what you guys have been doing with your journey or probably we should make a group club and study together one/twice weekly so we can see our progress by teaching each other with your knowledge (only suggestion). I don't want feel to be alone, lost in the ocean to study this. Happy learning!!!
