ummm.... okaaaaay.... so in past live's I've managed processor validation groups, including at Intel, so if somebody came in and hand-assembled X86_64 code right before my eyes, I'd think "Great! Most people have to learn that on the job." Being able to disassemble X86_64 in your head is a valuable skill, too. For my next question I'd probably move on to asking them how to create a particular pattern of I-cache misses. And for bonus points, write out the bits of pi as a 32 bit float.
