When analysing your interview material, ask yourself:
What human qualities are most influential in shaping the way this person lives and works?
Which quality or trait proves most beneficial or most troublesome?
Were there any major turning points in this person's life/career?And how might these have affected major decisions?
An older person or mentor is often very important in shaping the lives of people by providing guidance and encouragement. To what extent was this true of your person?
Many people act out of a "code" or a set of beliefs which dictate choices. It may be religion or politics or a personal philosophy. To what extent did your person act by a code or act independently of any set of beliefs? Were there times when the code was challenged and impossible to follow?
