The forum is really helpful, it gives you very detailed idea about the process.
My advice would be to just take the points from the forum but not to get tensed about them as each case is unique from consulate perspective to analyze on their parameters to either approve the visa or not.
One point I felt is that they seems to have already analyzed the case, interview seems to be final recheck of the candidate because my interview hardly last for 2-3 minutes.
Additionally I feel Visa type and company applying your Visa too have importance/impact as in my case question to me were very less.
How is it at Mumbai Consulate?
1. Literally we have many people applying for US as compared to other countries, so you would see huge queue outside the consulate
2. After getting in at gates of consulate there is security check (mobiles, car's electronic keys are not allowed). Most importantly there is no locker facility (at least i did not saw any)
3. After security check there is huge lawn where candidates are seated before getting into the actual interview hall
4. After getting into interview hall, candidates has to go through the finger scan and then wait for their turn (no token system its one after other)
I was standing in queue as officer was interviewing candidates in front of me (they were for L1 & L2, married), as they left i was called.
As I reached the counter I greeted the officer, good morning sir.
Officer : Good morning, can i see your passport.
Me : Here it is
Officer : Which company you are working for? (At first i did not heard it properly so asked to pardon)
Me : XXXXX
Officer : Are you a manager or going for Special Knowledge
Me : Special Knowledge
Officer : What is it
Me : I was briefing the officer, he saw me once in between and then glanced through passport and said Your Visa is approved, you will get your passport in 3 days.
Me : Oh, thank you sir and have a great day ahead.
Today on 2nd Dec 2015 I got the passport back as well, the Visa is stamped for 5 years.
