Citrin and Smith draw upon extensive experience in executive
recruiting (and we're talking CEO searches for _big_ companies here!)
to describe the career patterns for high-level executives. Not really
my career path, but people who are interested in rising to the top
through a mix of potential-based promotions (up) and experience-based
promotions (generally sideways) will do well to read this book.
