This book is by Tetsuya Ishikawa. I am only up to chapter 4, but seems like an interesting read.

As the title suggests, it's by a guy who was in the world of investment banking who gives a relatively easy to read account of his tales and experiences in an industry that caused the "credit crunch".

My favourite quote so far is his mentor giving him this tidbit of advice:

"The problem with analysts is that they don't think like investment bankers. They're great at doing everything they're told but that won't get them very far. You have to always be thinking about 'how do I make money?', 'is what I'm doing right now making money?', prioritising everything on the basis of how you're going to make the most money, and if you're doing something that won't make money, you shouldn't be doing it. Think about that, Andrew, think about it."
