The Interview is with 2 management pilots, Fleet Managers or possibly Fleet Manager and Chief or Dep Pilot. It is a very relaxed affair, one will be making notes in the corner of your responses, the other asking the questions. These are mainly geared to get to know you, your career to date, last type, type of flying, which fleet you would be interested in, why, etc etc.
Afterwards, there is the time to ask any questions you may have regarding employment with Monarch, T's and C's etc. Although many companies now offer a very similar package, others do have scheduling agreements and not as conservative management. Alot of opportunities have been missed on alot of scheduled routes when Monarch should be market leaders.That being said, it is a good company to work for, very friendly crews and alot of invaluable experience to be gained. I would suggest though, if you have the hours and experience for the likes of BA,Virgin/Emirates I would go there or spend 3 years gaining experience on the 320 and moving on from Monarch.Many have turned down Monarch in favour of EasyJet for this reason, alot of hours in a short period.
Best of luck with the interview though.
