The Consulate was very flexible changing my date. I 've got a date one month before the original one.
I had the inetview at 9.00, I had to wait approx 1 hour after submitting some extra papers.
The Interview itself contained 5-6 questions (basic ones eg. where did you meet, have you met his parents...etc) while the consul was typing something on the computer . He was quite friendly and polite , ask some question about my work in Hungary, than he told me that I should come back at 3.00 pm to pick-up my visa.
Everything went smooth and organized.Good experience.
