Here's the thing I think you're missing when it comes to the employer's POV during these types of interviews: they don't care so much about your skillset. At the point where you're doing an in-person interview and being asked these pointless puzzle questions, they are reasonably sure you have the required skillset to do the job.

What they're actually testing for during the in-person interview is your ability to be a good worker bee. They're filtering out people like you who would question the point of doing task X. They want people who will do task X without question. They don't want workers who will ask "Why are we doing task X? Shouldn't we do task Y instead?" For most positions at these large companies, the person who questions the efficacy of task X is a different role -- the role that is instructing you to do task X.

With these trivia questions, they are in fact telling you as a prospective employee the kinds of tasks you will be doing. They are letting you know that you will be doing a lot of pointless work, you won't have any say in the work you will be doing, the work you will be doing will seem trivial to you, and you have to be okay with that. If you're not okay with that, it's not the job for you.
