When people set their minds to something, it’s hard to change them. That is true in life and it is true in executive search when a board determines the type of CEO they want to hire. I see it often in the staffing industry where a company intently focuses on hiring leadership talent only from within their domain. If their focus is light industrial (LI), they want a CEO out of LI. If their focus is healthcare, they are determined to keep their candidate lists clear of any talent outside of healthcare staffing.
