In the team-based environment at Air New Zealand that the cargo team works in, there may be times where you have to take the bull by the horns and be the leader of the team. While your interviewer will be able to see any formal leadership positions you've held during your career, they'll be looking to hear the details of the leadership role that you took and what you learned from that experience that will be beneficial to their team. If you don't have any formal leadership experience on your resume, there is no need to fret. Prior to your interview, think about times where you've taken the lead on the job and discuss those in detail.
