L1, L2 Visa

I got my L1B blanket visa approved. I applied along with my wife and daughter. Below is my experience:

History: My B1 visa was refused 3 times in past and I dont hold B1 visa.

Since, we had our kid with us, we did not have to stand in queue anywhere except at fraud detection fee payment window. The whole process was completed in 40-50 minutes.

After arranging the documents and making 3 sets, I paid fraud detection fee through credit card. My first card did not work as the bank considered it as suspicious transaction because of USD and sent a message to my mobile to verify the transaction. Since mobiles are not allowed, I could not verify it and then used another card which worked. I will suggest to carry multiple cards including debit cards for back-up or carry cash or DD.

Here is how it went:

Me: Good morning
VO: Good morning, she is very cute (after looking at my daughter)

VO: Could you please give me papers and passports?
Me: Given

VO: Will you work at client side in US or at ABC office (my company which is a product based company)
Me: ABC, which is our head office.

VO: How many years have you worked with ABC?
Me: 9 years

VO: What salary will you get in US?
Me: xxx USD as base salary and yy% of base as annual bonus.

VO: Is it xxx USD? (She confirmed again)
Me: Yes

VO: What are you going to work in US?
Me: I will be working as an architect for XYZ product. I will be responsible for design and development of core components of XYZ and will work closely with business team to create and design the architecture of the product.

VO: Where are you going in US? Tell me city and state both.
Me: YYYYY, CA

VO: What are your roles and responsibilities in India?
Me: I am architect of AAA product which is previous generation of XYZ.....

VO: How many team members in India?
Me: I lead the development team in India, we have X developers in the team. I will be the first one in US for this work.

To my wife:

VO: Mam, are you working?
yes

VO: What do you do?
told

VO: Do you have any other kid?
No

After this she stamped all 3 sets, gave me back two sets and said: Your visa is approved, keep these sets safe with you.

I feel the answers for specialization and US work should be simple enough for VO to understand. Be genuine, respond confidently, do not give much details in first answers, keep it crisp in 1-2 lines and provide more details if asked. Write your answers on paper and read it multiple times to look for any follow up questions.
