Business Visa - B1

This is my first interview experience at the US Consulate, Kolkata.
 An African American lady took my interview.
  Greeted Good Morning (With a Smile)
She greeted back ( with a smile too)

> Why are travelling to US?
      I am going for a Conference (XVZ) with my parents.
> Can I see your invitation letter please?
     Gave the letter
> How long is your stay?
    2 weeks..
> Which places have you visited earlier?
   Told her..
   Then she was interrupted by her colleague for something.. Shuts off the MIC and close the drawer.
      Waited for few minutes before she continues..
   After waiting for like 5 mins, she continued..
> What are you working?
    Told her the answer
> What is your job?
    Told her the answer
> Who is sponsoring your trip?
    My father
> How much does your father earns?
   Told her the amount
> What is your father working as?
    Gave her the answer..
> How much you earn monthly?
    Told her my income..
   That's about it!! She told me those beautiful words " Thank you sir, your visa has been approved!"

   I was so happy coming out of the US embassy, I was nervous a bit when she couldn't understand one of my answer... I thought oh damn.. im not gonna get it.. somehow she understood and continued with the interview... i was also nervous before my turn came because the person in front of me had her Visa on hold for a while.. but as soon as the consulate smiled greeting me, I was confident answering her questions..
