OAA = Oxford Aviation Academy
Some are good some are bad. There seems to be no average operator, the guys I flew with (As Capt) where either extremely sharp or so bad that it made me think if one can buy a licence or obtain it from a box of cornflakes?
One common denominator is the huge cultural divide between Westeners and people CIS countries and the very basic command of English language. My better half being Ukrainian I am dealing with this daily. However in the Cockpit and cabin alike this means more often than not, misunderstandings and conflicts resulting from the above.
Another problem is the Soviet style system where you need to have a millions of papers and stamps to operate an aircraft. The whole CAA structure run by old Aeroflot muppets will not change, though it needs to, until the last of the old school have gone.
