It's the same thing that happens with tech certifications which are providing a similar service. It often doesn't tell you anything unless you happen to know and are familiar with the ones that have value. It does make it harder to read a resume or get a good feel for a candidate. They may be able to say the right things but without the true insight that makes it valuable. It often can land you with someone who understands the motions but didn't develop the intuition. It's one of those weird self selecting groups- the people who think they need a bootcamp or a technical certification to get the job might not not be the right type of person to begin with, is instructed the wrong sort of way, or ends up with the illusion that they are near the end of their learning rather then just starting at the beginning. On the other hand there are people who really make the most of it and come out extraordinarily better. But those top of class folks are by definition a minority. Other people succeed, but don't exceed. Other people pass. It's the same reason why some people devalue college graduates.
