I'm 22 and have been unemployed for a few months now. I recently had a handful of on-site interviews, all of which I didn't pass. I quit my previous job due to management issues and general workplace issues that were exceptionally abnormal (apologies for the vagueness, but I don't want to be too identifiable).
I'm currently living with my parents and recovering from the emotional exhaustion of it all. To me, at least, rejection itself isn't the real issue -- if I could get rejected quickly and regularly that would be ideal for finding a better match. The issue for me is more so the social and emotional fatigue of getting genuinely interested in the companies I interviewed at and going through the 5-8 hour on-site process (which, in general, I've actually enjoyed -- most of the people I've met with at the interviews have been quite fun to talk with).
I think it's a shame that hiring isn't more efficient. I find searching through job lists soul-crushingly boring and incredibly tedious. Especially because many jobs throw around certain technologies as buzzwords and don't (and likely don't have any intention of) actually using them, making search engines very ineffective as well.
I miss working on teams and getting things done in the way that only teams can, but so far that hasn't outweighed my general apathy towards the process to continue.
So I do think that the hiring process is broken, if only for the existence of people that are bored and would be happy to work just for its own sake. I'm in the process of becoming more active in some FOSS projects I care about but I find working from my room a lot less productive than a proper office environment.
