And all credit to BA for their recruitment policy - it is how it should be done.
From first hand experience KLM (and the VNV) do not follow the same rules.
The way that they treated the, generally, British pilots in the takeover of Air UK/KLMuk some years ago was disgraceful.
Compare the KLM takeover of AirUK to the way that British Airways integrated Cityflyer Express at LGW - no comparison.
One more reason to vote out.
