When answering behavioral interivew questions, the STAR technique. STAR is an acronym that stands for "Situation" , "Task" , "Action" "Result".
Situation - When and where did this take place? What was your role? What problems occured in this situation that you had to face?
Task-What needed to be done? Was there a deadline? Was there a crisis?
Action- What specifically did you do in this situation? (Describe in detail).
Result-What was the result ( crisis averted? increased sales?)
When answering, be explicit, so the emploer has a clear picture of what you can actually do.
Give examples, and tell stories. Describe how you demonstrated certain key skills in a specific situation. Illustrate concretely that you are ready to do the job and can take on different situations.
