The New York Times wrote a juicy article on Apple University, the internal Apple training department for Apple employees. 

About Communicating at Apple, one of the available courses:

You go through more iterations until you can simply deliver your message in a very concise way, and that is true to the Apple brand and everything we do,” recalled one person who took the course.

This is fascinating stuff for any Apple present and past user. 

In broader terms, it’s essential that a company seeds its core values with its employees straight after onboarding. Apple University seems very well planned and thorough.
