Sorry, what? You seriously think some people's coding skill depends on the writing medium? That's not what the OP was saying: they said they didn't know how to create a linked list from scratch, whether they were writing on a whiteboard, a computer or with a crayon on the back of a 4000 year old cuneiform tablet from Mesopotamia.
Is it that you just don't like the kind of problems that are being asked (fundamental computer science) and would rather see more real-world problems? Or do you genuinely think the wide, stubby pen and vertical orientation impairs some people's coding ability? Just to note, I can see the performance aspect of the whiteboard is stressful, but coding on a machine with everyone looking at you is stressful too.
