I think, nowadays, I can get a generative AI to tell anyone how the process of inverting a binary tree works, and perhaps even give sample code for it.

So that's not interesting to me at all as a person hiring engineers.

What I want to know is "how have you solved bigger design problems" or "what's your approach to keeping code maintainable and reducing cost of ownership"

I've also hired people who 3 other managers have passed on and those people have gone on to amazing things at the company in which I work.

So the process is horribly broken... it doesn't successfully weed out anyone, and we've also hired really toxic individuals also with the same processes.
