I am making a generalisation, based on having interviewed over 200 developers in the past 2 years as part of technical screening.
80%+ of the bootcampers were rubbish and shocked to be told their knowledge was way below where they thought it was.
A classic is a 6 week JavaScript bootcamp grad claiming to be an "expert in JavaScript" (their words) and couldn't explain the JS type system or basics of variable scope. That was the norm. That kind of rubbish.
I'm happy you're an exception and everyone gets a fair chance with me, regardless of background, but I am never shocked when I have to bin yet another bootcampers CV
