One of the things that amuses me most is ex-FAANG engineers who are absolutely stymied when they don't have access to the tools and support systems available at their former employers. They've never had to deal with some of the very rough systems the rest of us deal with on a daily basis just to make the business run.

Hubris runs rampant in the ex-FAANG crowd, and businesses who aren't tech companies who hire these folks do so precisely because they don't understand that what worked at ex-FAANG won't necessarily translate to their business.
