I would like to reply to the statement that some company like BA would not take guys coming from Ryanair:
If it were really the case, why invite them on the selections anyway???? It doesn't make sence to let people come over for the selections if you know beforehand you are gonna turn them down....
Now if nobody from Ryanair had been invited in the first place, that would have been a different story.... but it's not the case!
