I feel like I'm either losing my mind or people are being deliberately obtuse now.

He's not saying they ask you to give a full overview of the way Apple architects their systems, he's saying they ask you to explain how a basic Kubernetes deployment might look, or how you might go about setting up some kind of backup system, or literally any of a million different technical things that you might have knowledge of and interest in.

How could things like this possibly be under NDA? If you weren't able to use any of this knowledge, you would be completely crippled in your work.
