from what I can gather, the recruiters send your file to Dubai with a little note saying they either would or would not recommend hiring you. The final decision lies at Dubai but I think thats just a formality. The recruiters are the ones who met you and spoke to you so I think they get a massive say in it.
But dont worry, I dont think anyone comes out of an interview (for ANY company) feeling like they did really well. People always focus on the bad and think about what they could've done better. You did really well to even get to the FI so they mustve seen something in you they liked. Just wait and see
