My Atlanta DO interview experience today was very similar to the recent descriptions by Sethumadhavan and msatl in regard to the time spent with the IO. My IO was very professional and efficient in manner. His demeanor was pleasant, even friendly, but there was no time for chit-chat. Our encounter was very businesslike. After swearing me in he went through my N-400 confirming my answers to every question. I'd taken a summer vacation trip out of the country since my filing, so I was asked to write in the info on that trip in the section of the N-400 about that. I wasn't asked for a single item from my extensive portfolio of extra evidence (passports, tax returns, etc.).
Since English is my first language and I previously learned basic US history and civics through helping my daughter study for tests at school, I had no trouble with the Civics and English tests. (Questions I recall were date of the Declaration of Independence, one of the longest rivers, name of the first 10 amendments to the Constitution).
At the end the IO said he was recommending my application for approval, congratulated me and asked if I would be able to attend an Oath Ceremony on August 27th. This is the part of my experience that's a bit different from recent posts. My interview appointment was in the afternoon, so I was expecting that it would be too late for a same day Oath. That was especially true by the time I was called for my interview, about an hour after my appointment time. It's not surprising that the office might start falling behind their appointment schedule by afternoon.
Despite the long wait in the waiting room (and then another, shorter wait for my file to be verified so that the OL could be issued to me), like everyone else, I'm really happy and content to have made it past this momentous step.
From my experience, I'd advise other forum members from Atlanta that if you get an afternoon appointment:
1. You may have a long wait in the waiting room. (I recommend bringing along something to read, to pass the time).
2. Don't assume your Oath Ceremony will be scheduled for the same day or even the same week. This might be important to know if you're making travel plans.
Good luck to all upcoming interviewees!
