The interview gave me a big surprise. They had lost my joint sponsor's documents from the file. The girl was quite nice and barely asked me 2-3 questions regarding my relationship like where did you get married and how did you meet. And she said we are not denying you I just need you to send me these papers and we will send you the visa. They did send it to me a week after I mailed them the papers again. But that day I was very depressed.
