Your success stories should include the situation, the action you took and
the result. Here is an example if you were interviewing for a sales
position:
The Situation: I had a customer who did not want to hear
about the features of my merchandise because of a prior interaction with my
company.
The Action: I listened to her story and made sure I heard
her complaint. I then explained how I would have handled the situation
differently and how I can offer her better service. I showed her some facts that
changed her mind about dealing with the company again.
The Result: She not only bought the merchandise, but also
complimented how I handled her account. She is now one of my best customers.
