Hey Craic,
Don't EVER think there's anything wrong with you girl!!!! Nobody really knows how airline interviews work, and hey, look at you and what you've already achieved!!!! You've just passed training with another airline, and you're officially cabin crew!!! You've done great to get where you are, so don't ever think there's anything wrong with you!
P.S. How are you settling in? Hope everything's good for you over there, and don't worry, I'll be in your boat soon too!! I'm so scared!!!

hahaha, but excited too!!
Keep your head up and enjoy flying!
