I agree that Google has many unique internal systems for job management, workflow management, authorization, CI/CD, etc., that have unique configuration and unique behavior that new employees will need to learn. As an SRE you probably spend a lot of time in that world. Seems like the linked article was more on the topic of programming languages, though, not configuration management. I don't think a non-Googler would have any trouble reading and understanding Google internal code in a programming language they're familiar with. Exceptions might be pre-TypeScript JS codebases using the closure compiler annotations, old ndb Python code if there's any of that left, or Java engineers who haven't used dependency injection before.
