They might, for example, decide to demonstrate one aspect of their communication skills without asking clarifying questions by showing that they can, on the fly, produce a high-level summary of what happens when you load a URL followed by orderly expansions of each of the steps involved in increasing levels of detail. I've been listening to people expound their theories of interviewing for decades now, and very often they have some pet idea which involves asking the candidate for something and then trying to deduce information indirectly from how they interpret the request. I think these theories are pretty much all bad ideas, because what the candidate is actually doing is trying to guess what the interviewer wants to hear.
