Be careful this might lead to temptation to speak negatively of something or someone. When you are mentally framing your answer be sure to turn it around to give a positive spin/response. Don't see this as an opportunity to deride others who may be slow or less experienced. Whilst it may be difficult the answer could lead to you explaining how you enjoy helping others where they may need it. This may help the job to progress more smoothly and also improve the less experienced and knowledgeable person's ability to complete the required tasks.
