They will give offer letter when u cleared interview in india. When u reach saudi they will give another agreement copy which is not matching your salary. For example your original offer letter mentioned SR 8000 means your original agreement copy mentioned only SR 800 .which means they are cheating the saudi govt.if you not agree that contract immediately they will stop you salary untill sign the SR 800 salary
