When answering a behaviour based interview question remember to describe the situation, describe how you reacted to the situation and describe the end result of your action. You might also want to get references from previous employers.

When describing a situation, you should ask yourself:
•What was the situation?
•What were you doing?
•What were the circumstances?

When describing your reactions and actions to the situation, ask yourself:
•What actions did you take?
•What specifically did you do?
•How did you handle that?

When describing the end results, ask yourself:
•What results did you get?
•How did the other person respond?
•What kind of reaction did you receive?
