I accept your point, but another side might be that they want a "new" pilot without any preconceived ideas on how it should be done.
It is also more likely that the "new" pilot will stay with the company longer..as you can see, there are several ways to look at it.
As someone who is involved in these aspects of aviation, I can assure you that not every experienced pilot is prepared to "do it the company way" and this can cause distress amongst longer serving pilots etc etc...
If it ain't broke, don't fix it!
