You actually describe my day job pretty accurately. SAP based legacy systems where everything from system variables to customer codebase is this weird mix of English and German. Strict project guidelines and code review sessions can only catch part of this mess before it's rolled into production.

We have junior devs come and go that simply look problems up online, because they are able to translate their questions into proper English, that the senior German-only devs would spend days trying to work out by themselves. Or they somehow find the same solutions online but can't make sense of what Google Translate spits out for them. It's equally hilarious and sad to see a junior dev being used as a seniors LetMeGoogleThatForYou.
