H1B, H4 Visa

Nov 26th L fingerprints
Nov 27th: Visa interview at 8 AM
Reached consulate at 7:30
security check completed by 7:45 and entered inside at 8 AM

couple before be were tourist visa, they didnt get visa because they dont have I797 copy of their children
next to my counter before me was H1B visa, He didnt get Visa because he confused about his salary.. he said initially monthly salary and took time to calculate yearlt..

My experince(EVC model):
Me: Good morning office
VO: Good morning
VO; Are you working for xyz company
Me: Yes officer
VO: Howlong you are working for this company
Me: X years
VO: who is your end client
me: ABC
VO:Which location you are working
Me: Y City, N State (My work location was remote, i was working from home completely, so entered complete address including apt# in DS160, but said only City and State Name in interview because don't want to get additional question saying full address )
VO: How much your yearly salary
VO: tell me about your project
Me: Explained briefly
Me: xyzK/anum
VO; Your Visa has been approved.
Me: Thank you officer.
