Activity is the signal. Self taught but goes to a ton of meetups. Enrolled in one of the legit online master's programs, etc. Ofttimes bootcamps can appear on these resumes. Someone did a bootcamp, realized it wasn't enough and kept growing in a manner.
People who treat the bootcamp as the terminal level of knowledge plateau.
Can't the same be said for University? I know lots of classmates who didn't do anything outside of what's mandatory. They wouldn't have a GitHub account if they weren't forced to in a class for example.
