Pay close attention to what made that boss the best in the candidate's mind. You have the chance to determine if the people in your organization will meet her standards. If she describes a supervisor who walked the floor daily and got involved in every project, and your management team sits behind closed doors, you may want to think twice about this hire. If she describes someone who never micro-managed and gave lots of opportunity for professional and personal development, then you need to be certain that you can provide an equal or better experience. Good people don't leave jobs; they leave people.
