That's really impressive but you sell yourself short. You did do the college stuff just not in CS but in a related difficult field.
And then you had ultra high discipline to work hard for 3 years on top of that to break into software engineering. You didn't skip the process you just did it a bit differently but roughly in the same ballpark of difficulty,
> My bonafides: I’m a college drop-out with a background in mathematics who went from teaching and having almost no coding experience to working at a big tech company in SV in ~3 years. The result is not typical, but I’ve seen it repeated enough to know that I’m not just a fluke. I recently saw another college drop-out make the jump in 18 months.
