I would however imagine them to need to be able to show good skills at communicating the things they actually do, and being good at communicating that is in itself a skill that they will not necessarily use on a daily basis.

Yes, that's called an interview. No one is saying there is no need to interview... So you seem to agree that leetcode style questions are irrelevant and pointless?
Yes, I do, but the comment you replied to above also made the point that those kinds of questions are not the primary reason why you need to practice interview skills, so it's an odd thing to focus on.
