Go read the literature on Hack Reactor. They double load their students with learning to code (better (assumed they are not 100% green)) and with how to perform in the job. They also help with interviewing 101 in an applied sense. Imagine getting a job based on knowing how to code, but without knowing how to pass normalized interviews that many teams simply assume people have insights and experience around.

I am not affiliated with HR and have not met them, but I like their approach on paper and could see it making a big difference. I have met people who have graduated from different programs. Some are ready, but that is largely a product of the person...not the program. I do not feel as confident about all programs generally.

I think what you are thinking is that people get knowledge, but not capability but things do not have to happen that way.
