Recruitment process in Hamad General Hospital for Admin

hi all, I just have some questions to those people who had been hired or waiting for the recruitment process in Hamad Gen. Hosp... I was interviewed last June, locally here in qatar, im husband sponsor, after a week I received an email from them & luckily I was considered for the position in Admin & told me the hr will contact me for my recruitment. After 2 months, Aug. the HR contacted me & ask for some documents to formalized my recruitment, and now its Oct., im still waiting for the HR for their another email for the status of my recruitment process or for a job offer, i kept on sending emails for follow up to them but there's no reply.
My questions are, how long does it take for the recruitment process in Hamad? The HR will ever don't mind to reply for  following up for the status of recruitment? how long do i need to wait for this, do you have some idea? its been 4 months already since my acceptance & interview has been made.
