I finished reading the sample and was mildly impressed. Still as the topic is of interest to me, I was on the fence about buying this book till something caught my eye. All the reviews for this book are 5 stars. That is totally fine except that all of them seem to be from people who are very new to reviewing things on amazon. For 5 out of those 8 people who gave it a 5 star, this is a first review. And from what they say, this book looks like the holy grail of getting in to a tech company!
Call me a skeptic but I ain't throwing my money at something that looks like it's trying to drum up some fake publicity.
