I’ve followed and part-time mentored several people through their self-taught education. There are a lot of pitfalls and traps that can send people down the wrong path if they’re not careful.

One that I did not expect but that seems obvious in retrospect: It’s really easy to start reading Reddit or watching Twitch streams of developers ranting about the industry and think that actual skills don’t matter any more. There’s a temptation to think that you’re a fool to study and practice the job skills because what you really need to do is optimize for interview skills. So they drop everything and starting grinding LeetCode, putting unfinished “side projects” on their GitHub that have all the right things in the README.md (just hope nobody actually looks at the code) and memorizing S.T.A.R. format responses for the common behavioral interview questions.

This strategy actually worked reasonable well for a few years, but the game has changed and most companies are better at catching professional interviewers who don’t know how to do much else.

I should note that this mindset isn’t unique to self-taught people: There’s a parallel epidemic of cheating in college among students who see it as “just a piece of paper” and think they’d be foolish to actually learn the subject material. This also hits hard when they reach graduation and are faced with the current style of interviews which are not as easy as they expected to bluff your way through.
