H1B, H4 Visa

Hi guys,
 The forum has been a huge help for me to soothe my nerves before the H4 visa interview. so, i would like to do the same for others out there. I've tried to be as detailed as possible.

Background: First time applying for H4. I already have a B1/B2 tourist visa and have traveled to the US multiple times. Got married three months ago. My husband has an h1b that will expire in 8 months.

Firstly, a mistake: After filling up the DS-160 form and while scheduling the interview, i unknowingly clicked on the "are you a child below 14 years" tab. Hence, it automatically directed me to the dropbox option. Thinking it was a stroke of luck i went to the designated one in Kochi only to be told I had to go to the chennai consulate. they very kindly cancelled the dropbox and I went home and quickly scheduled a date. DONOT PAY THE VISA FEE AGAIN. the staff at the dropbox facility also told me to change the ds-160 as the city of issue in my passport was bangalore and not new name of bengaluru as i had written in the ds-160.

Note: When you change something on a completed and locked DS-160, the application number changes. be sure to make that change while scheduling the interview.

Two weeks later in Chennai..

Day 1: Ten printing. Turned up 5 mins before time of 13.15 pm and they allowed me to enter immediately. Have in hand passport, DS-160 and appointment letter. Walked up a flight of steps to the first floor, a room with cubicles. Was given a token with a number and when your number appears on the screen go to the counter mentioned. They ask for passport.

Day 2: Visa interview Chennai consulate

1.Again turn up only 15 mins beforehand. You will not need to wait at all outside if you do that.
Ensure your passport is in hand. They will scan the barcode before you enter.

2. Security check in an outbuilding (u can take umbrellas and bags but no phones/usb. only, you will have to keep it all on the steps inside the consulate). Long queue. When I reached the front, one of the staff members gave me a "know your rights" pamphlet and asked me if i have my husbands i797 form. I replied yes.
3. More queue to get into the consulate. Almost an hour long wait in three queues

4. Finally reached a counter where they ask for your passport. they mark the aforementioned barcode with a coloured pen

5. Next proceed to a counter where they scan the four fingers in your right hand.
Question: What is your husband's name. Reply appropriately.
Again a mark on barcode with a diffrent color pen.

6. Proceed to the actual queue for the visa interview. Another half hour in queue
