Yes, trading companies and even trading divisions at banks.

I've interviewed at plenty of them (only one in recent years, though) and while I wouldn't say they were easy, they aren't doing completely irrelevant challenges like leetcode.

I've certainly never studied for one, unless you count flipping through a book or two just to remind myself of things I may not have thought about in a while. Like 1-3 hours tops.
