Normally, it takes around one week for a temporary visa to be issued, such that you can enter the country. The rest of the process like Medical, Police Clearance, etc.. happens once you are in the country, which takes another 3-4 weeks before you get your Qatar ID. There may be some problem with your visa, or they may have applied just before the Eid holidays. Have you worked in Qatar before, and have not yet completed two years since you have left the country?. That could be another issue. If the person is saying, its in process... it probably is in process and you should wait till you get it, unless you have another offer in hand.
