I've had similar problems. We've had some bootcamp grads who were good to work with and acknowledged that they were still very junior. We've also had some bootcamp grads who felt entitled to mid-range to senior compensation after their first year, while still getting their bearings on basic developer work. It's hard to explain that, no, I will not give them a raise to match what we're paying people with 5+ years of experience after their bootcamp promised them $200K comp after a couple years in the industry.
