My apologies groundhog. The post was written in about 15 seconds before I had to leave for work!
Interview process was as follows:
1st day sim check - raw data 747-400, ADF tracking, holding, ILS appoach to minimums
2nd day exams - planning exam, tech exam (general ATPL type questions - multi choice)
3rd day interview
4th day group exercise - introduce yourself to group, select who to interview for Air New Zealand from several CVs
My impression is that once you have the interview you're OK - you have to "talk yourself out of the job". The hard jobs getting the interview.
