Is this not already common knowledge? It's taught pretty extensively in one of the required lower div CS classes at my university, and it's usually in other schools' curriculums from what I've seen.
It's kind of depressing, but I've adjusted how I ask my problem since it's not actually needed to demonstrate the skills I want to see. It doesn't take long to learn bit manipulation when it's needed, even though it seems like a foundation of computing to me.
Indistinguishable from "can't really integrate shit" without some hours of relearning.
