what is the job title you were offered?

if you don't mind, can you provide details of the package?

from what i have seen on this site, no matter what they are giving you for accomodation, it won't be enough, so unless they are giving you an apartment, part of your salary will go to rent.

cars seem reasonable (at least compared to Egypt - i'm thinking of making the move to Doha too).

other expenses will probably average out to something comparable to Dubai.
