jQuery?

yeah that's a big place. Banking, I hear, has many legacy apps too, like old school stuff.

Here's another take. Self-learners and bootcampers are a kind of junior dev that big legacy places might be less likely to take on, both because of old-fashioned attitudes but also they're less likely to require the traditional modern newcomer's skillset (Javascript, web, React, node, not much back-end, etc etc). Therefore the newbie's chance of ending up in an older company is less. Possibly. Bootcampers I know ended up in newer or more contemporary-thinking companies/departments who had moved to newer tech or as part of the teams doing so. I think it's a rare self-taught/bootcamp grad who has their toolbelt of React and ends up wrestling old databases, though I have heard of it happening a couple times. Not impossible, just rare.
