Not sure about the alphabet. Got to K before I got stuck and thought... So in that moment, if I forget that there's kill that starts with a K, why does it matter? How does it relate to the fact that I know to use kill for sending signals? The recall for a situation where you'd use something and for a letter matching game seem to be very separate. (On the other hand I remembered join which I used maybe once in my life...)

It's multi-faceted. It shows your ability to think quick and how you solve multiple problems. If you stop in the middle of the list and try over and over to come up with an answer, how will you react to a real problem? Or do you just give up when it gets hard?

It's testing more than just rote memorization. You also have to explain any commands you write down, what they do.
