How would you know they are a bootcamp person? Technically I'm a "bootcamp person" since I went to school for EE and not CS (so I'm mostly self taught when it comes to programming anything that isn't C), but that isn't something you would ever know about me without asking. I would imagine there are a ton of people in the industry with similar stories.

Bootcamp people being easily noticeable would seem to require them to be noticeably terrible in some way. I'm not sure you break into tech that way. My projects and technical interview skills were way ahead of the average CS graduate at the time precisely because I was a "bootcamp person" and couldn't rely on the degree.
