I'm a financial engineering student at an Ivy League institution. Just got the book from Amazon. Awesome book, so far the best help in preparing for technical aspect of the ib (quantitative positions) interviews that I have encountered. I thought it would be sort of a black and white xerox copy - instead it turned out to be really well published. The book is rather weighty (>300p), contains a plethora of questions with detailed explanations, 0 filler. The guy is very good about cultivating the attitude of, "It's the thinking process and not the number in the answer." Overall, I would definitely recommed this. Given the amount of general info you can garner off free advice sites - vault/wetfeet, this may as well be the number one book on your preparation list.
