The particular positions that I'm hiring for require certain kinds of knowledge, unfortunately. When one is dealing with Petabytes of structured signal data, it's helpful (but not required) that someone know memory layout. But, it's not the first question I ask.

Usually, I start off with some behavioral, get-to-know-them type questions. One of these is to ask them to recall the 'best software developer' that they've ever worked with. The great majority of candidates actually say themselves which is unexpected (and a little arrogant to me - weren't we all 'junior' developers once? - didn't we all once look up to someone?). But, surely one of the best would know when to use an array and when not to or know the memory and precision impacts of the variable types that they use.
