757 or 767 Rating is not the same rating anymore !!!
According to an urgent job vacancy, pilots rated on B757/767 are urgently welcome if they got the minimum requirements on B757 and B757 ONLY. You can get as many hours and experience on 767, I am afraid the company would not shortlist your application.
What - a - joke. Who are they to pretend that 767 pilots are too stupid to drive a 757 caravan.(Actually they are the one paying you at the end of the month and taking advantage of that) Sorry but the JAA certifies those two aircrafts in one rating so don't try to be more clever.
Next step will be, "We are looking for B767-300 (but not -200), then 300ER (but not 300) then 300ER with pink toilet and green curtain rated pilots..."
Aviation is ruled by idiots who play with puppets...
