H1B, H4 Visa

Hi Guys!
I had my visa interview on 20th May at Chennai Consulate and i got the visa and want to thanks this forum for the valuable support.
Here r my interview experience..
I had my interview schedule at 11.15 and i went to the consulate around 10:40 and have to wait in queue for around 15 minutes and i get inside, my documents have been verified by VFS and they give me blue folder , one thing to notice due to change in dollar's value i have to pay extra 62 Rs as visa fees so, before going to interview check the exact visa fee in indian currency.
After that they send me into visa lobby, there i have to wait for around four hours becaus out of seven counters only four was working and out of thoes two was for different language, then i got my turn .Visa officer was a youg ,charming guy , i went there and wished him , he also replied warmly and asked for blue folder which i had given and then asked few questions those are:
Where r u working?
What is ur role?
What is ur highes degree and when u finished it?
What is the project for u going to US?
Is it inhose project or clent side ?
Which country u visited before?
 Then he saie u will get ur visa within a week have a nice flight.

TIPs: Don't be tensed, give ur answer confidently, ur answer should be to the poin and short, don't hesitate to ask if u won't understand the question and last but not least believe in God and pray to him because ultimately he decides....
