H1B, H4 Visa

Hi All,
I'd like to first thank immihelp and all its users for sharing their experiences. It's my turn now.. :)
My wife and I attended the interview on 16-Aug-2010.
This is how it went...
We reached the consulate at 10.15A.M (scheduled time of interview was 10.45)
At the main gate we were asked to show the passports and the interview letter, after going through we were let in.
Then we joined a queue with about 15ppl ahead of us, when our turn came, we were given a tray and were asked to put all the documents,belt metal bangles, walet, keys etc in the tray and then were let in for scanning.
Then all our items were given back to us and were asked to proceed.
Then we were guided to a counter where we got our documents (that were submitted with the vfs application center) back.
Then we joined the queue for finger-print scanning (this queue was long and wait time here was more) after finger-print scanning we were given a token number and were asked to wait in the waiting area, here again we had to wait for abt 15-20 mins. then our number was called and we were sent to join a queue for the final interview
