How competitive are you?
Being a competitive person is an excellent thing if you are appropriately competitive in the workplace. Assure the interviewer that you have a tremendous competitive edge when necessary but are still able to balance that competition healthily.
"I think that on a scale of 1-10, I would rate myself as a 7 when it comes to being competitive. I love a great competition in the workplace when it comes to sales goals and breaking through last years' numbers. I am not competitive to the point that it would hurt my team or colleagues."
"I am not overly competitive when it comes to my ego. My competitive nature kicks in when I have a deadline to meet or a client who wants to be impressed by my level of work and service."
