L1, L2 Visa

First of all thanks to Immihelp site for helping with L1B questions and individual experiences.
Now its my turn to share my experiences :

My interview is scheduled for 27th August 2019 at 10:30 AM. I am not going to explain Biometrics part here as that is self sufficient and a very smooth process.

It was a big queue and I don't know why people reach so early. I saw lines which was scheduled for 11:30 AM also.
It was pretty smooth process overall. We entered exactly at 10:30 AM where we asked to make 3 sets as follows :
1) I129S (First 8 pages)
2) I797 (Only 1st page)
3) DS160 of primary applicant only.
4) Passport of primary applicant.(If you are accompanied with someone else , consulate officer will ask separately to provide the passports.)

I paid the Fraud and detection fees via credit card and then moved to line where the actual INTERVIEW happens.

Below are few questions which lasted for 5 mins :

1) Who is your petitioner?
ZZZ
2) Where are you going?
YYY
3) What will your US salary?
$$ZZZk
3) What is your knowledge specialiaztion?
SME in this and that product. Here ans should be unique for everybody depending on individual expertise.
4) Will you be working for client?
No

To my Wife:

VO : Can I have your passport mam?
1) How long you are married madam?
2) Do you have kids?
3) Is this your first time in US?

Key things to be noted :
Be confident and relax for interview. Have enough sleep one night before. Prepare for your answers and review them until you get satisfied with your answers.

Salary and Product based company will be the additional advantage according to me.
Now I am waiting for my passport for collection.

Best of luck guys. Do well.
