Interviews exist in this weird space disconnected from the reality of the work and being judged by those closest to the work. Not many real on-the-job situations would require someone, for example, to be able to recall the protocol number for a given protocol without looking it up, yet that's one of the questions that a particular very famous tech company has their recruiters ask, and you get auto-rejected for not knowing. It's unfortunate when a place becomes so large and so desirable that they'd rather force people to try multiple times to get through an arbitrary obstacle course and succeed on some combination of chance and skill vs attempting to more honestly assess if a given candidate could actually succeed in the role they're hiring for.

I hate 'trivia' interviews with 'gotcha' questions dealing with experiences their team may have recently dealt with (and probably took weeks to identify/resolve).

I would say the port/protocol memorization may be required depending on what job you are interviewing for. If its for a tech support job, maybe the ports/protocol question is pointless.
