Open your answer with a general Statement. This should be one or two sentences in direct response to the question. Amplify this with a few more details. Then give a few examples to prove your generalizations. This is the most important part of the answer.
Interviewers remember specific examples.
They don't remember generalizations. In your example be specific, provide results, and describe your actual role. Wrap up your answer with a summary statement. Most candidates end their answer in the middle of paragraph. Practice the two-minute response before your next interview.
