I passed my interview today in Mt. Laurel, NJ.
Super smooth experience, got there, checked in and was called by the officer about 15 min later. She was friendly and it felt more like a conversation than an actual interview. She started with reviewing my form and corrected some info at my request (I traveled overseas during the Holidays). No vocabulary/ definition questions asked. Then we moved on to the civics questions and the reading/writing portion. I was asked to review the Oath of Allegiance and sign that I was willing to take it. Then I was told I passed the interview and that they were having an oath ceremony in about 1hr so I could be part of it, if I wanted. The ceremony itself was about 25min.
All in all, I was in the FO for about 3hr and left as a citizen! As others said, the naturalization has been the smoothest and fastest process in my journey immigration: from form submission to oath ceremony it was exactly 107 days.
Good luck to all!
