Same here. I would have to study up for the interview and that seems pretty silly considering I spend every day writing code and have for years. There's a lot of irony in that too considering that when I need a b-tree, I Google it.
It would be funny to bring an Android phone to a Google interview and then proceed to Google answers for questions they ask like this to point out how outdated the question is.
If it's anything like interviews at my company, we just aren't really trained on how to interview, so these questions come up because the interviewer may not know what to ask aside from things like this, and their last interview experience may have been when looking for a job straight out of college when this was all they really knew about, so this is what interviewers asked them about. In a way those questions may just be "what you're supposed to ask someone in a CS related interview".
