H1B, H4 Visa

I attended visa interview in Chennai on 17 Oct. My interview was scheduled at 11:15.
But I was there by 9:15 am and asked the security regarding time. He said time is not an issue. I can go inside.
I saw lot of guys from companies like TCS, Infosys come in ties with their ID cards hanging around necks etc.. Found it funny though..
First they checked the interview letter and passport and I was let in .. got security cleared and went to the pre processing section.
Here Indian employees check the from 156 and 157 and passport and keep all this into an folder and asked me to proceed to the next building.
btw I had multiple visas to US before ( 1 B1/B2 and 2 H1 ) and also visited euro union countries.
When I proceeded to next bulding, they took finger printing and then i proceeded to window.
Me: Good Morning
VO: Good Morning. How are doing
Me: fine thank you.
I handed over the folder with PP & forms 156 157.
VO scanned through them occassionaly staring at me ( my be to judge something )
he then starting looking something in the system.
VO: You already travelled to US
Me: Yes
after 3-4 min pause
VO: Are you married
Me: Yes. Also have 3 yr old son
VO: is you family going with you?
Me: No
VO: Have a pleasant flight!
Me: Thanks a lot.

Thats it. I was outside by 9:45 am. and i am waiting for my passport to check visa details.
