At one of my old gigs, I asked my then-colleague a bunch of questions about the codebase for a task I was assigned. He was always like "you are a senior resource, you should not ask such questions; if you want to find answers, look into the code itself." This is how he keeps his status and job at that company, and he is still there now. When I enquired around about how he got that tribal knowledge of that codebase, I got a fascinating answer: he asked his ex-colleagues at the same company, the same kind of questions I asked.

Unless one joins as an intern at some company, there are gatekeepers in most of the companies, who don't want to train you at all. Instead, they criticize any attempt to find answers as "hand-holding, fake, inexperienced, etc."
