Doesn't sound like your type of company tbh, the flipside is that a "serious" company will often have broken bs too except now nobody is going to look at your contribution/fix.
"your type of company" sod off. Meta is only like this because its got a massive advertising revenue stream.
the sheer amount of engineering time wasted because we don't document stuff is astounding.
For example, how many message queue systems do we have?
how many half arsed message queues have been created because they didn't know about FOQS?
