Just my guess, but about 70% chance you receive company accommodation on joining, and if you do it will be fully furnished, ( at least Holiday Villa was) but styles seem to vary depending on the compound......
May be able to research some of bigger ones like Ain Khalid gate,
Holiday villa, and recently started putting some people in nicer areas like the Pearl Qatar.
Otherwise FO will receive 13000 Qr and CA 15000 riyal per month for housing
