I got that book. While the questions and answers are useful, in my experience this book alone is nowhere near enough to get prepared for a Google interview (not that the author claims that).
I studied CLRS's Introduction to Algorithms and a couple of other books for about 2 months. Even then I could not answer the hardest questions during the onsite interview. And if you cannot come up with an optimal algorithm for a given problem, all of the items mentioned in the article (communication, clear coding, testing) don't really matter.
