English Teaching role offered in UAE with Ministry of Education but which City?

I have been offered a role to teach English in the UAE as part of the Ministry of Education reform.

I wanted to know what is the process from here? I have already sent all relevant documents what is the next step after this? Also, did you have a choice of which city to work in and did it get allocated to you?

I have chosen to work in Dubai but they confirmed I will not find out my school until I arrive in the UAE. I assume they already place you in the school prior to this, does anyone know when this may be so I can express my preferred location?

Also, general tips/advice on life in UAE and accommodation, living costs etc.
