After applying for citizenship early January 2016, followed by biometrics mid February 2016, and then nothing at all until June 2017 (yes, 2017!) when my interview was scheduled, despite a very straightforward application, I became a US citizen Thursday last week! Awesome ceremony and a great speech by the judge presiding over it.

Well, it was 16 months between the biometrics and the interview, so that was on par with the rest I suppose ;-)

Sure. 
 
The interview was pretty chill. The USCIS officer was very friendly and acknowledged that my processing time was surprisingly long and she couldn't see why. 
We chatted for 15min or so. She asked me a bunch of questions about my recent travels, if anything had changed in my application recently etc. Then the 'test' started.
The English test basically was 'read this sentence' and 'write this sentence'. I thought it was funny since we had been chatting for 15min or so. 
Then she asked me 6 questions from the 100. Since I answered all of them there was no need to ask 10. I was given a paper saying that it was all good (I forgot the phrasing exactly, but it's along the lines of you're approved). 
A couple of days later my status changed on the USCIS site saying that a letter would be sent with time and day for the oath ceremony. It still took over 2 months between the interview and the oath.
 
The oath took about 3hrs. I arrived with 38 other applicants. The first 1h30 was in a room where they called us one by one to check if anything pertaining to travel abroad, marital status, criminal record etc has changed since the interview. I had travel abroad for a few days so I brought my passport as proof (the oath letter tells you what to bring for the ceremony). It was merely a whole bunch of waiting, and an officer telling us how we would proceed. Then we went to the courtroom where friends and family were, and the ceremony itself lasted an hour or so. 
Couple of speeches (from the judge, various organizations in town, an invited speaker) then the oath, then the pledge of allegiance. And I was able to register to vote immediately after that.
