I can understand in these environments they want to limit risks. And because the work is boring and the conditions are average to begin with, these companies are always on a massive roll of junior developers. It's especially bad if code isn't their main area of expertise.

I've seen companies of 300-500 employees struggle to keep even a single senior programmer over half a decade. They'd get far more talent by actually embracing an engineering culture. What I always see is that the juniors start getting experience, realize the place they work at is a huge pop culture and leave for an engineering one, thus lowering the talent pool of said company.

Basically they don't want smart engineers, they want replaceable code monkeys. They have yet to realize there's a few orders of magnitude worth of quality and productivity between the two.

I used to work in such an environment until I had enough of this cancer and decided to move to a small studio with less than 30 employees but with a very strong engineering culture.
