Within the first ten pages, it is clear that the author is pandering to McKinsey without providing honest insight into the company or top notch consulting. Come to find out, the author only worked at McKinsey for 3 years.Waste of a book unless you are beginning in business consulting. Even then, much better books on the market. Should be titled Consulting 101.
