To be clear, I'm not saying one shouldn't prepare for these interviews and that there aren't very clear things that interviewers are evaluating on. There is an optimal solution and you should prepare for it.

What I'm saying is that your mindset is another differentiator. If you go in with the mindset that the interview is a waste of time and that your interviewer is trying to trip you up, you've walked into an interview with a toxic mindset. I'd be willing to guarantee no one anywhere wants to hire someone with a toxic mindset.
