a) that's survivorship bias - for every one who "worked" on those frameworks and got somewhere because of it, there are thousands who wasted their time.

Hint: these are people who don't have interviews. They go for lunch. Or dinner. > It's the same principle as the guy who interviewed at Google, Facebook, Airbnb & dozen other companies and then used several offers he got to negotiate and he ended up with ridiculously good package for software engineer. That's an imaginary guy.
