I'm already well aware of best practices and I was really surprised that they didn't have any documentation or anything.

I meant, is going to school for CS worth working at a place like that.

They really aren't willing to make changes, as I said the goal is to push out apps as quickly as possible.

Coming from my previous job, where I was the only developer, I have full jsdocs/phpdocs, quite a few tests and high level user manuals. They have nothing resembling that.
