As a consultant, I have to say that this is true of our industry as well. Our company has always been full remote due to the "on site" nature of our work. Given that, it has always been a pain point to spend time mentoring and training. many hours of zoom calls for training just doesn't foment the kind of quick Q&A than in person does. For us, the net effect has been that the people who do well tend to be autodidactic to at least some degree.
