Right. I just had my phone interview yesterday with the NY office. He asked a lot of questions and I sort of rambled on as well and just told him everything, but he mostly asked:
1) How did we meet?
2) Where did we meet?
3) Where are we getting married?
4) What do my parents think about getting married so soon?
5) How well off are we financially?
6) What does my fiance do for a living?
7) Where are we going to live?

How many physical days have we spent together?
9) How have we kept in touch?
Every question I answered with a full in-depth answer. I also just sort of talked- told him about my fiance and our life and what we had planned for the future. He also asked me if I had any questions for him and he was really nice. I think the key is just being honest. They do this for a living and they know when someone is lieing so just tell the truth and you will be fine.
I got the Visa approval via email 1 hour after the telephone interview
