I totally agree with this comment. The questions he asks sound really old school to me. This interview style seems very academic, you should focus on their technical maturity for the role, and wonder if they'll be productive in a real world scenario (with Google). I find this sort of gotcha questions pointless.

I like to gauge the maturity of candidates, but I make sure to never use gotcha questions. I propose them comfortable real world scenarios, and help them show the best of their thought process.

I've interviewed many people who were very good at answering this kind of theoretical questions but were short on delivery when I proposed them the test project supposed to demonstrate how readily they use these concepts in real world situations.

Quite frankly, it looks like the author has the graduate syndrome : http://read.reddy.today/read/10/the-graduate-syndrome
