Just as everyone else has said, the interview at the Embassy is the easiest part.
In Vancouver, be sure to arrive 15 minutes before your appointment time, they won't let you in any sooner. My appointment was at 1 pm and I had to wait until 12:45 before they were letting people into the building, I guess all the officers were still on lunch.
Make sure you have all your documents requested on your checklist and you will be fine. The interview part for me was 3 question:
How did you meet?
When did you get engaged?
When is your wedding?
They also asked what my fiance did for work, how much salary he made, what kind of work I did and how much I made. As well as would I be working in the US once I was able to.
The lady told me right away I was approved and to come back the next day to pick up my Visa.
