Job interview question for an entry-level front end developer: "Reproduce the work of four Turing award winners in the next thirty minutes. You have a dirty whiteboard and a dry pen. Your time begins... now."
I have actually done this. I bought myself a pack of premium pens at an art store and kept them in my laptop bag for customer site visits. They were designed for writing on glass but also worked great on whiteboards. It’s fun when your diagrams just look better than anyone else’s. It’s like a report document with good typography. It can be filled with made up BS but it still impresses subconsciously.
