Business Visa - B1

I went to chennai for VISA processing. It was a 2 day schedule. The first day was biometric scanning which got completed in 15-20 min and the next day was interview with the Consulate member.

My appointment was @10:00AM, I went to US consulate at 9:30. I have to stand in the line outside the US consulate for 1hr, by the time I entered the consulate it was 10:45 and again inside there was a big line.
I spent another 45min in the line. Finally, my interview started at 11:30

The interview process:
Me: Good Morning Ma'am.
VO: Good Morning Sir.

VO: Why are you travelling to US?
Me: To attend business meeting and technical discussion about company product(tell the exact product)

VO: which place in US are you visiting?
Me: I am visiting Palo Alto, California

VO: What is your designation in the company?
Me: I am working as Senior Member of Technical Staff

VO: How long have you been in the company?
Me: I have been in the company for __ years(tell the exact number in year and month)

VO: Do you have any family in US?
Me: No

VO: How long will you stay in the US?
Me: I will be staying there for 2 weeks

VO: Thank you Sir, your VISA is approved.

My initial plan was to travel on June 3 and I had filled the same in the application form, but because of 30 days waiting time for the appointment it got postponed. I was expecting some questions on this? But they didn't ask, even if they would have asked, My reply was it was a tentative date and the new date of travel will be in the 2nd week of July.

The overall experience of VISA interview was good, but somehow they have to manage the long waiting queue.
