most people get their visa without an interview these days, mainly because they don't want people coming to the embassy,a small number are asked to attend an interview, some appear to be just at random, others are asked to bring more information or to clarify something, but even then many who go for an interview are told they have their visa straight after the interview..
so don't worry if you don't get called for one, and don't worry too much if you do
on here i would say 95%+ of people are successful at getting their fiancée or spouse visa, just provide the information your asked for and read the forum for tips and advice, and you should not fail
