I think he's referring to those white board coding sessions where the interviewer forgets that you're a human being and not a dog.

"Draw Spunky" as a reference to the ubiquitous "If you can draw Tippy, you can be an artist!" ads in the back of comic books where a kid would connect the dots to form a turtle and then send five bucks to some fly-by-night diploma mill.

I'm guessing this is a psych/creativity test about drawing an abstract concept, like courage. "Spunky" would then be the abstract concept of spunkiness.

I guess the Americans here may be blissfully unaware that this word could have other connotations on the right-hand side of the pond.
