Prototyping, for one. Thought process. Creative thinking. Knowledge of relevant material.

It may not do these better than other tests, but basically any "solve this in x minutes" questions are going to reveal behavior in a person.

Why does crate thinking have to done fast? I find my best and most creative solutions come randomly after thinking about them "in the background" for a while.

It doesn't, you must not have read what I wrote.

But if I can do the same creative thinking faster than you can, why would anyone bother waiting for you?
