During your interview with Air New Zealand, you will want to show the interviewer that you work well with every personality, even though you recognize there are some folks out there who are quite difficult to please. This can be a challenging question to answer, but it can be done with class. Think about the person who is seen as hard to please or the person that people are easily intimidated by. Tell the interviewer what made this person challenging, along with what your relationship was with them. Be sure to mention a few positive things about the person as well, while still making your point. Next, share how you feel your responsibility is to work well with your team and help out however you can, so you chose to adapt to work with this challenging person. Finally, be sure to laugh a little about the situation along the way. It will definitely lighten the mood and show the interviewer you understand some people can be challenging.
