And don't for one minute think that other airlines are not going to copy FR once they see how it goes - it's been the norm in the States for many years and you can bet that the big boys like BA etc would love to cut their high cost of recruitment and selection.
To be fair, a large part of the problem is due to the high number of 'chancers' who will send in their CVs for just about anything regardless of whether or not they are qualified plus a fairly significant number of people who will tailor their CV to what they think the recipient wants to see. This means that there's a cost entailed with weeding those people out - and I suspect that having to hand over a monkey does a pretty good job!
