I am in the same situation as well. I don't know how exactly they process. I remember some of my friends have applied for a research center (at Algiers too) and they have been replied months later (up to 2 months). Thus, maybe it will take similar or more times; because CDTA has opened a great deal of positions, over 70s at baba hassen only. Or maybe the recruitment is yet over, this is what I begun to think since a couple of weeks. Anyways, it would be very helpful if all guys who have applied keep us updated with this issue. Sincerly, yours.
