Do you enjoy being a leader? The hiring manager will want to know if leadership is a path that you are hoping and/or willing to take as you grow within their company.
"We recently brought on a summer student and I was asked to have that student shadow me throughout that time. I really enjoyed teaching her the ropes and also found that her questions challenged my knowledge and memory on certain topics. I am very comfortable taking on a leadership/mentorship role and am happy to do so."
