Unfortunately feedback has a price: senior engineers have to do more thorough code reviews, they may have to explain more fundamental things, and it all adds up

Unfortunately feedback has a price: senior engineers have to do more thorough code reviews, they may have to explain more fundamental things, and it all adds up. Some junior devs are independent and learn quickly with minimal feedback. Bless these devs, I love working with them. Some junior devs require a lot of time, and make the same mistakes over and over.
