I agree with the reviewer who pointed out that, because it is largely a puzzle-book, it is significantly more challenging as an audiobook than it would be in written form. But I would also point out that if you can't handle this book as an audiobook, then you're probably not smart enough to work at Google. If you are considering this book because you really are contemplating a job interview, you will receive these or similar puzzles orally, not in written form. Don't be afraid to challenge yourself by doing something that's a little more difficult. The book is perfectly comprehensible, even without ever actually referring to the PDF at all.
