I'd bet that if all of the current pilots on the list were told, "you have to come in to the training center in 6 weeks and pass the current newhire interview process so study up." that less than 50% would pass.

From a strictly HR perspective you are much more likely to get a quality long term employee from a place like endeavor where you can verify their performance as an EMPLOYEE over the last 5-10 years than you are on interviewing someone that you may not have access to their 5-10 year history. Everyone looks like a good employee in an interview, not everyone is a good employee.

Do I think they should just come over with a records check, no. However, if that happens to be the case I don't think that it will make a noticeable difference to the pilot group 20 years down the road.
