At the highest levels, you may have to interview with many, many people - often with a panel. Be knowledgeable about the organization and its history as a word-class pediatric medical center. Appreciate the business side of medical care providers and the influence of healthcare reform. If meeting with scientists or physicians, know what they do. If you are in research and/or medical profession, know what those at CCHMC have done in that particular area. Look online and in the news. There is much there.
