Haha, almost everything at Apple that is not seen by the user is full of crap (and increasingly you see user facing bugs and schedule slippage too). Possibly still somewhat true in hardware, but in software, they have far worse engineering practices than Google: remember "goto fail"?

Back in Snow Leopard days you could instantly crash the kernel with a fuzzer. In fact I managed to do that accidentally by hand. NT kernel had much more systemic hardening than XNU.

Apple also treats employees capriciously and in non-standard ways. Your experience is almost entirely dependent on who your manager is. I have never heard any of big tech make so many false promises to employees. I have friends who negotiated for an immediate green card application upfront, but they later found out they were bait and switched, etc.
