I'm making this review on behalf of my Fiance who had his interview today:
His appointment time was 9:00, so he arrived to queue at 8:00 after first going to Gould's to check in his keys and phone, and have his photos taken. Was let in to Embassy around 8:30 and proceeded to wait until 11:00 before his number was even called! He went to a window where his documents were taken for review (and complimented for our organization!) He then waited another half hour or so before he met with an American gentleman from the Embassy who asked just a few questions as to our wedding plans, and Tims plans once he arrives in the states as far as what type of work he'd pursue (he is a teacher). He then said everything was in order, took Tim's passport, and told us we're in!
A little bit of a wait, but all in all a smooth experience.
