Sorry, I just saw your message today.
It looks like you passed, congrats!
My interview was extremely straightforward, started with the civics question and as soon as I got the first 6 questions right she moved on to the written test.
After that, I was asked the usual questions (ever been arrested, military training, etc). Once that was done, the officer explained how the Oath ceremony works and told me I should expect a letter in the mail in the next month or so.
I was not asked for any documents, just my interview letter before entering the building.
