They also do not invest in their workforce the way other Bay Area companies do. For example, they do not really encourage engineers to grow outside hired abilities and make it almost impossible to find time to work on anything except the Radars (tasks) put in front of you. Plenty of managers would proudly say out-loud they would prefer someone go build a new skillset outside of Apple and then come back. (This is jokingly referred to as your "next tour of duty" as many engineers actually do come back.)

They also make it challenging to switch teams internally, you basically compete for the same role an external candidate would, and you interview as if you were an external candidate.

All of that makes it very easy to get burnt out and so either you are someone bought into the "cult" of Apple and couldn't see yourself working anywhere else, or you peace-out once the rose-colored glasses come off.

low pay?
