Ironically not watching the video because it's too long, but a large part of the reason why a lot of games are bad is because they're too long. Or, more specifically, because the developers choose to pad out the playtimes with meaningless sidequests, enormous (and completely empty) open worlds, collectathons that give your character an extra outfit if you find all 4900 of the shiny rocks the developers had some algorithm autopopulate the world with, and basically every other AAA trope that doesn't involve well-polished, purposeful gameplay or story.
And they do this because the industry has repeatedly doubled down on "more content == better" dollar-per-hour metrics. There are plenty of games out there that actually take 120 hours to beat (looking at you, Persona) that are legitimately great games because they fill those hours with engaging storylines, characters, and mechanics (some grinding aside).
Interviews are a Byzantine nightmare made up by HR people that have no idea what that job entails, let alone how to interview people for it. Companies put up fake job postings often to make themselves look better, not bothering to tell candidates that they're interviewing for a position that never existed at all.
You are not the problem, never were, and you will find a job. I'm sorry you have to deal with the shittiness that is the job market, and I promise you most if not all of us have been there before.
