Describe the action you took and be sure to keep the focus on you. Even if you are discussing a group project or effort, describe what you did -- not the efforts of the team. Don't tell what you might do, tell what you did.
Action you took
Results you achieved
Describe the situation that you were in and the tasks that you needed to accomplish. You must describe a specific event or situation, not a generalized description of what you have done in the past. Be sure to give enough detail for the interviewer to understand. This situation can be from a previous job, from a volunteer experience, a school project or any relevant event.
Behavior Based Interviews
Behavior based interviewing is a technique in which the questions asked assist the employer in making predictions about a potential employee’s future success. This is based on actual past behaviors, instead of based on responses to hypothetical questions. In behavior based interviews you are asked to give specific examples of when you demonstrated particular behaviors or skills. Behavior based questions typically start out by asking you to give an example, tell about a time when, or describe a situation. A strategy for answering behavior based questions is a technique known as S.T.A.R.
What happened? What were the results? How did the event end? What did you accomplish? What did you learn?
