@array@AndyScott I also have a humanities background, and didn't learn any STEM after my freshman year of college (I got a C in Calc I). A few years ago I decided to change direction and did a six-month coding bootcamp.
I now work on very low level development for the flagship product of a leading tech company.
I was only in my 30s when I did the course but some of my classmates were older and found good jobs in the field.
