If you have no kids be aware of the accomodation situation. My wife and me ended up in an apartment on the 29th floor of a tower block on S.Z. Road with bright pink bathrooms and 300 cabin crew living underneath us. As we had given up a nice, detached house back home to come here my wife was less than impressed. As has been mentioned before you don't get any choice with the accomodation and you stay in a tower block until you get a command. However long that takes....
On a brighter note the accomodation allowance (if you move out) has gone up 10% recently and is now merely inadequate instead of completely useless.
At least we are saving money on education.
