Applied for B1/B2

VO: What is the purpose of your trip

Me: 12 day planned vacation to the east coast with my wife

Me: Yes

Have you been international before?

Me: Yes I have(mentioned 6 countries in my ds160 - Malaysia, Vietnam, bali, sri lanka, qatar, Azerbaijan)

What did i do wrong? If he asked i would have presented a 8 lakh balance bank account, i followed the tips from here to not overshare on things

The VO was super chill he approved all the visas before mine

What did i do wrong and what can i do when i reapply next time? When should i?
