7This is the only book on hiring that blends the research on levels of work with the discipline of behavioral interviewing. Every role has a level of decision making, a level of problem solving. The research on levels of work, pioneered by the late Dr. Elliott Jaques, is powerful science. The discipline of behavioral interviewing is the most effective method for its application. This is the only book that puts these two ideas together in a practical framework for managers faced with the hiring decision.
