To a great extent, the continued success of Catholic health care organizations is dependent on the selection of co-workers and leaders who are committed to carrying on the organization's mission. The Sisters of Mercy Health System, St. Louis, uses three tools to help leaders be more consistent and objective in assessing employment candidates for organizational fit. The first tool involves behavioral-based interviewing, which looks at a candidate's potential for future behaviors based on his or her past behaviors. The second tool assesses a candidate's values in such a way that accounts for and reduces the interviewer's own subjectivity. And the third tool-values-based interviewing-helps reveal a candidate's natural aptitude for, interest in, and personal agreement with the organization's charism, religious heritage, and values.
