Hi. First of All, Million thanks to Immihelp. It couldn't have been possible without your help. The questions and answer posted by many of the users were of great help indeed.
Firstly, I'd like to tell everybody that I filled DS 160 on my own, not taken any help from any of the travel agents or visa consultants. Didn't do any formal training. I had applied for tourist visa along with my wife and my two years old daughter. Following were the questions asked :
Date Oct 14, 2015. Time 8 AM.
Language : English
VO : Good Morning
We : Good Morning Sir!
VO : Passport please
Me : Sure Sir
VO : Why do you want to travel to US?
Me : For tourism
VO : What do you do for living?
Me : Explained my job profile (Working in leading Pvt Bank as Branch Manager)
VO : What's your highest qualification?
Me : Masters in Mathematics
VO : Do you have any relatives in US?
Me : Yes, Wife's cousin
VO : Which place?
Me : Explained
VO : Where does he work?
Me : Explained
VO : Have you got your leaves approved?
Me : Yes
Then, he started to type for almost 30 seconds.
VO : Do you own a car?
Me : Yes (Told brand and model name)
Next, he started asking questions from my wife
VO : What do you do Ma'am?
Wife : Explained (Asst. Professor)
VO : Higest qualification?
Wife : Masters in Computer applications
VO : Which subjects do you teach?
Wife : Explained
Then came the golden words, Your visa is approved. You can collect your VIsa from our Visa Centre.
Now, time for few tips :
Be confident, don't lie, don't get nervous. We didn't do any prepartion for Visa interview, it was like just a formal discussion. So, be yourself and look straight into the Visa Officer's eyes while talking.
Secondly, If you believe in GOD, then keep telling yourself that
GOD IS WITH ME AND WHEN GOD IS WITH YOU, NOTHING WRONG CAN HAPPEN.
In your imagination, keep telling yourself that God is guiding you. God is with you in the interview as well and you'll feel the magic. I've applied this technique in my professional career as well, at the time of review meetings, during job interviews or any other important work or assignment that i take up, the results are always positive and in my favour. This tip has also worked wonders and I've changed the perception and negative thinking of many many people. Best of luck.
