It may not be the UAE, but when I chose to move to Ireland, they were on my radar...
DFS were not prepared to offer anything other than "their deal" and wouldn't budge; which IMHO was nothing like what I was worth and certainly didn't recognise my 17 years of ATC experience.
DFS had a better employment rep than the IAA but financially I couldn't justify it; I wasn't looking at making a mozza (or I would have gone to the UAE/Bahrain), but just getting a fair deal; I didn't want to go backwards financially, With the IAA I'm more or less even, with the DFS I would have been way behind.
But still I didn't spit the dummy for wasting my time, I just politely said thanks for the offer, it's not viable, I won't be coming...
