Interview was set at 7:30 AM.
We were up by 5:30 AM to get ready and prepare the kids.
We arrived at the USCIS office at 7:05 AM and they opened the door at 7:15 AM.
It was us and another lady. Then another woman and a gentleman arrived.
At 7:25 they called on my wife and of course did not allow any of us with her (unlike the green card interview).
After 5 minutes, they called the man, and the 2 ladies shortly. A 3rd woman arrived and went inside.
A nice lady (seemed russian) arrived and waited for 5 minuets before she was called.

Had my interview yesterday, Honolulu DO. It mostly consists of going over your entire application question by question, and checking that the answers you give under oath match what is on your application. I was asked some more detailed information which hadn't been mentioned on the application.
The interview ended with the tests of reading, writing and civics, which were quick and painless. (One sentence to read, one sentence to write, and six questions straight from the study booklet. The interviewer stopped at six, since I answered everything correctly)
I had my interview last week, and took my oath yesterday. I could have taken oath same day, but I requested a few days later for work scheduling issues. The IO had no problem honoring my request, and asked me which date I wanted.
