A few updates! My wife got her interview notice too. For whatever reason our interviews are one month apart even though we applied one day apart.
Also I am a citizen now! My interview was scheduled for 10:30am. I arrived at 10am, checked in and then spent over an hour sitting and waiting there. Interview was remote and pretty straightforward: test questions (didn't get anything hard, just a mix of easy and medium questions), read / write a trivial sentence and then the majority of time was spent going over n400. The person was friendly and I never got a sense that I have to remember everything 100% but they did go pretty thoroughly over my form, including branching off into a few details that I can best describe as an informal conversation / small talk around your form (e.g. hey where does your wife work? oh you worked at the same place, did you guys meet there? etc etc). After passing everything, I went downstairs, waited in the room for 30 mins and had a ceremony with several other people.
