Google doesn't ask these types of trivia questions. I don't believe that you were talking to a person from Google one bit.
Everything documented about their hiring practices and anecdotal evidence from people gone through their interview process is that you talk with a real engineer and write code for your interview.
I took a phone screen interview for SRE (site reliability engineer) at Google Dublin and the questions at the screen test were the same, almost to the word.
I don't know this guy but the questions he's talking about are genuine Google screen questions.
Questions in the later interviews (that is, if you pass the initial screen) are more complex, and involve actual coding or longer problem solving.
