My understanding of the point system, and I have nothing to do with recruitment is;
+Nepotism is Dead, no longer a factor for getting a job
+Age doesn't come into the equation, it is experience so if you have 10,000 hrs you are believed to be around 40ish.
+University degrees gives extra points. PhD may deduct point = an academic
+Qualifications eg LAME helps
The point requirements for being selected for an interview varies. It varies depending on what Air NZ is looking for in their pilots. Do they want older guys, to fill a void, are they looking for management pilots, or line drivers.
Best of luck for all of you waiting for a call.
