Try the C.A.R. Technique
When an employer asks you how you’ve tackled problems in the past, use C.A.R. (Challenge, Action, Results) statements to respond. Detail exactly the challenge you were up against, the action you took to address the challenge, and then the great results you achieved. C.A.R. responses help you communicate exactly what you’re capable of bringing to the table -- by clearly demonstrating what you’ve accomplished in the past.
