Me too i have received an invitation letter yesterday from the same school signed by the president of the school. Also I received the contracted which includes detailed information about my position, role, salary, accommodation..and signed and forwarded it back to them..and they asked me to contact a Dalma immigration services in Qatar...I don't whether it s a fake or scam..but what confusing me is that I am in constant contact with the school HR after I applied for the job position advertised on a website..!! any idea about this kind of work??!
