How to you filter out those who are genuinely interested in self learning and motivated to keep up with evolving software trends vs. salary chasers? And more importantly, how can someone from a self-taught background convey that they are not just chasing salaries, but have a real interest in this stuff?

I fear that there is a bias in the industry that bootcampers = salary chasers and CS undergrads = real deal, when I've seen (anecdotally) a huge uptick in people entering CS undergrad programs just for the high salaries fresh out of school.
