I had my interview recently(April 4th), I didn't know a few answers like how old the counter signer is and the date of birth for both my parents. I am absolutely awful with dates no matter how important they may be. The one question that stood out for me was if my Father was alive or not, all other questions about my parents were identical. It stood out for me because my Father passed away back in November.
I had my passport a few days later, Now just waiting for September to go to Poland with the girlfriend. The passport should get a lot of use over the next year or so as my girlfriend is doing a year abroad for her course at university.
