H1B, H4 Visa

I greeted the Visa Officer and handed over the Passport and the I-797 to him.
VO – Whom do you work for?
Me- said my Employer’s name (only)
VO-Who is the client you shall work for?
Me – There is no client, the petitioner is XX and I shall be working on an internal project.
VO – Where shall you be going in the US
Me – City and State
VO – Can you tell me something about the internal project that you shall be working on?
Me – I shall be participating in all phases of the SDLC starting from requirements analysis,design….
VO – Interrupted me ….No please specifically tell me about the product you shall be working on.
Me – I got extremely nervous here , I guess the VOs tone made me more nervous.I told him” We are building a product in the informatica product suite, that shall read data from an application databse and load the data in the cloud” (just said this line , although I could have carried on explaining but I decided to stop at this point)
There was a pause of 2 seconds.As though the VO wanted to hear more, but I decided not to explain un-necessarily unless required.
VO – Your visa is approved sir.
Me – I stood there for some white receipt, I had read about in journals on internet.But he didn;t give me any.I had received the rights pamphlet outside.
VO – Your Visa is approved sir, have a nice day.
Me-Thank you.
I came out of the embassy and didn’t stop for the courier services. Was too excited to stop.
