tldr: it's been a few years since I've run into anyone in the pool without a degree.
quixotic history aside, how rare is it to get contract work as sendev, devops(sysop ftw) or mid-pm at some F50 houses? My offers are usually about 60% of CS holders... but I'd rather do than don't. Could just be the market in Vancouver, probably a skill issue.
When it became evident how much developers were in demand and could earn, there was a flood of late millennials and zoomers into CS programs, so the percentage of self-taught dropped to nearly zero. For a while when demand for SWEs still exceeded supply, that was augmented by bootcamp grads because getting the entry level job had become the hardest part and a bootcamp was a signal of legitimacy.
Bigger companies without tech DNA are more likely than small companies or tech giants to insist on degrees. When hiring was tight, they might ignore that signal; but right now HMs are overwhelmed with applicants and filtering by degrees is just one way to whittle the field down to a size they can hope to wrangle.
And it’s common for people over 40 to get out of the field for one reason or another — or shift to consulting, typically as “fCTOs” rather than contract developers — so that older self-taught pool is shrinking.
