This question offers you the opportunity to discuss some of the characteristics that enable you to work well with your co-workers, supervisors, and clients. The ability of team members to collaborate effectively is critical to productivity and marketing success. Telling a story from your past is an effective way to communicate your strengths as a team member. Use the STAR (Situation, Task, Action, Result) interview response technique. In your answer, while you want to focus on how you helped the group achieve a resolution, try not to focus too much on your individual successes. Be sure to end on a positive note so that your interviewer sees you as a proactive problem-solver and a team player.
