Hi cyprienb,
I had to wait for 5 1/2 weeks before I received an outcome to my FI and I was unsuccessful. Those 5 1/2 weeks were the most stressful of my life! I had to find other ways of occupying my time and mind to not think about it. As difficult as it is, you just have to wait it out and accept that you have done all you possibly can for your application. I checked the recruitment portal at least twice daily and kept in contact with the others who had their FI on the same day. As hard as it is, you also need to not put your life on hold for the waiting process.
I spent a lot of that 5 1/2 weeks in the gym and in the boxing classes trying to vent my frustration at the waiting game! Now I am part of a new waiting game... waiting 12 months before I can reapply.
Hope this helps.
