Sample excellent response:
I have participated in several groups throughout my academic career. Recently, I had to work with a group in my statistics class, and I had some personality clashes with one of the group members. However, I realized the importance of completing the assignment in a prompt and efficient manner. I made it a point to put my differences aside and complete my part, along with offering assistance to the other group members. As a result, we finished our assignment without any conflict.
Also, remember the S-A-R (situation-action-result) technique and see a sample S-A-R story.
