Business Visa - B1

I went to US Visa interview on 26th May At Chennai Consulate. It was my first experience and I've been reading different experiences on this forum from last few months. I was nervous and tensed after reading those experiences.

My Short Bio - I'm a startup entrepreneur and I was selected for a delegation to US. I have previously travelled to 4 other countries including Europe.

The guy in front of me was rejected. (He was planning to go for a vacation.) Then the VO asked me to come forward.

Me : (Smiled)
VO : Passport Please.
(I gave the passport)

VO : Why are you going to the US?
Me : Travelling as part of a delegation program organized by YYYY .

VO : What is YYYY ?
Me : It's a (explained what it is)

VO : How did they select you?
Me : (I explained)

VO : Do you have an invitation letter or something?
Me : (I gave the letter.)

VO : So, what are you going to do in the US?
Me : I explained the agenda. And said that I've the detailed agenda. If you'd like to see it..
VO : Yes please
Me : (I gave the document).

VO : So, What is your company doing?
Me : We're working on YYYY and ZZZ.

VO : Yes, Please explain.
Me : I explained.

VO : (Looks interested), How are you going to monetize this?
Me : I explained. (He listened to me as if he was curious to know)

VO : How many people are there in your company?
Me : XX

VO : (Nods his head)
(Typing lot of things in his computer... Stares at the monitor.. Again typing..)

And then came the words - OK, I'm approving your Visa!

Me: (Smiling), Thank you!

My Advice - Be confident and answer clearly. You have to understand that there are some elibility criterias. Travel history, your job, purpose of travel everything counts. They are trained to presume all applicants are illegal immigrants. And they have 2 or 3 minutes to judge you. They deal with 100s of applications everyday. So, they have no time for detailed verification.
