Part of the problem is not just the questions themselves, but that you're asked to solve them under time pressure, with a bunch of people watching.

I've had trouble with "write a function to remove duplicates from an array without losing order". This is fairly trivial and I can write this with my eyes closed, but if you're so nervous that you can barely think straight ... yeah, then it gets tricky.

I have lots of anecdotes of stuff I failed during interviews that know I can do because I've literally done it before or since. I'm one of those senior developers who failed to write a for loop during interviews.
