ntello - thanks for sharing, getting some hope reading your post since i had my FI in May and so far i have not heard anything from them.
waiting time - i think that so long you do not get your reply you cannot say you have been selected or not. like i said am waiting for more than 3 months now and i have not heard anything yet - no email/no phone calls/no change of status!!!! for sure waiting kills but what to do, things not in our hands.
for the others going to their AD - well i may tell you about my AD
1st group discussion - introduce the person on your right plus discuss five places you would recommend someone to do/visit in your country and why.
2nd - english test (essay - a mistake we did and what we learnt from it)
3rd - group discussion - name 5 personalities of the 21st century and we also had to say we chose them among so many.
however do not prepare on some topics because questions may be related to anything - be prepared for the unexpected!!!
