Visitor Visa - B2

So I had my interview last week on Friday. I went for the 11 am appointment with the documents. I am a 25 year old single female who has never travelled abroad before. I tried to not be too hopeful while going in.

Here's how my conversation went:

Me: Hi
VO: *no response*
.... Silence.....

VO: May I have your passport?
*I hand it over*.... Silence.....
VO: What is the purpose of your visit?
Me: I am going to meet my... cousin... and brother-in-law, um- my cousin's husband in Atlanta, GA...
VO: How long do you intend your stay to be?
Me: About two weeks?
..... Silence.....
VO: *while looking at screen* Have you travelled abroad before? *looks at me*
Me: No, this is my first time
VO: *nods and types something while looking at the screen*
..... Silence..............
VO: What do you do?
Me: I am working at XYZ since the past 6 months
VO: *looks up from his screen* 6 months..... And what were you you doing before that?
Me: I was a student till last year.... *VO makes a face* I graduated last year only! (I quickly added this)
VO: And what school did you go to?
Me: ABC University... It is located in ABC...?
VO: Who do you live with here in India?
Me: My parents. I am an only child.
VO: *nods and types*
..... Silence of several seconds.... VO was continously typing something
VO: Your friend's husband lives there?
Me: No, no, no he is my cousin's HUSBAND! He is my brother-in-law. Wait a sec, I have an invitation letter from him. He works at Deloitte on an H1B? *show him the letter*
VO studied it for a few seconds and started typing something for a long time. I was standing there awkwardly when he said suddenly, "Your visa has been approved, have a pleasant trip" and smiled for the first time during our entire convo.
Me: Thank you *smile*

I thought that my interview was a bit awkward. I was thankfully not asked for many documents and although he asked me stuff, I tried to answer in the least number of words possible.

My tip is that there a lot of people who talk TOO much and the VOs can't do anything but be polite. Like, try to tell and fix your behavior if you feel like the VO is getting annoyed. Some people carry on talking while the officers are typing. People should remember that the VO isn't simply issuing a visa, but they likely have to take down and maintain notes on the whole thing as well.

Be confident, be precise and have a good reason to as to why you are visiting. Don't try to be too convincing because that might tick off the officer and speak only as much as required. If the officer is chatty then you may reciprocate that.
