The engineering team at Air New Zealand must be masters of their trade in all aspects of the mechanics of a working aircraft. With this mastery comes the need to be very handy with the tools of the trade. This is an open-ended question that allows you to talk about what you feel is the most important tool in your success on the job. As you prepare for this question, make sure that your answer directly relates to the duties you will be performing in this role and, if possible, try to point out a unique skill you have with the tool you decide to talk about. This will help potentially distinguish you from other mechanics interviewing for the job.
