L1, L2 Visa

Interview Date: 15th June, 10am
Visa Status: Approved
Received the passport with VISA stamp on 17th June @ Bangalore VFS office

As mentioned by others, the waiting time is too much and interview time is very less. We were staying in the hotel right opposite to consulate office so just took 2 mints to reach the place.

We joined the queue @ 9:15am and entered the first door (D1) only at 10:10am. - total 55 mints
scanned all documents ( full security checkup) and enterered the second door (D2)
then one gentleman will ask what kind of visa. If you say L1B, then he will make us sit in differnt place and asks us to give three copies of ( I-129, first page of I-797), passport, DD and interview appointment letter
he will fold nicely and put one rubber band (please keep in the same order)
join the Q and exit from Dorr 3 (D3) - total 30 mints
Go outside and wait for another 30-40 mints
then enter another heavy door (D4).
Here your DD will be collected and the receipt will be added to the previously collected documents
Move to next counter and verify the finger prints
move to another counter to verify the passport. This gentleman will wish us "all the best for interview"
now joined the actual interview Q. It was like a snake and spent almost 30-40 mints (since its AC room it was ok). Fun part is we can see how the interview is going on for others
then sit on some chair for 10-20 mints
Now you will be sent for the interview.

I was in the assumption that we will be allowed to sit and discuss. after going there I saw that its a different story. They make us stand infront of glass door and interview.

Questions were general and very simple. Total interview was just 10 mints.

Question to me:

VO> Good morning
VO> Give me your passport
VO> Give me your papers
VO> where do you work?
VO> for how long?
VO> Whats your specialization?
VO> Why are you going to US?
VO> Why you?
VO> how long you will be in US?
VO> Salary

Questions to wife:
VO> How long you been married
VO> When is your anniversary
VO> How old is your son?
VO> Good that you didnt get him here, otherwise he would have freaked by looking at the crowd.
(long smile)

finally
I am approving your visa , give me 2 mints and I will finish paper work.

We came out @ 12 noon and had nice lunch at Dindigul Thalappakatti Restaurant

As others mentioned, the key points are
- be confident
