I see jobs listing a crapload of environments/languages in exp. Required like: -SSH -Git -Subversion -JIRA/Confluence -Java -Agile Frameworks ... and like 15 other points. Yet the diploma asked is not even university level (here there is a level of education between secondary school and uni, and it is the min asked)

Now my personal case is I got a 2 year diploma in a post secondary CS program. However I never got an actual job in the domain. I ended up working on my own videogames in Unity, developing skills in C# but not much else. With office admin jobs in between.

Seeing job offers like that just make me think I'm way out of my league, and since I never could get an entry-level job and familiarize myself with a CS job in a company environment I'm not suited for these, even though I as a person am pretty adaptive, good learner and amazing at finding solutions.

Am I right or am I overthinking this? Would I just be trained anyway if ever hired or is it a no-no if I don't actually have the experience and applying is a waste of time and energy?
