Interview experience:
IO was very nice and she came out side called our name and walked us in to her office. She was pleasant to talk to made few jokes during our interview.

first we took an oath.

Then she asked my wife how we got married and when we got married. she asked for wedding pictures and marriage certificate. Then asked for proof that we live together (joint bank accounst, joint house lease etc)
Our last entry date to United states.
Then she asked me about my job title, salary,company name and how many employees we have in the company. Then asked for my offer letter and supplement J. that's it. (She did not ask me about my paystubs or w2 or any other job related questions.)
Then went through the whole 1485 appplication with as and asked Yes/No questions. (make sure you know what you have in there)
I was expecting she would ask more questions but she didnt and it kind of got me worried. At the end she said they will let me know in 6 - 8 weeks. Not gona lie next fews days were tough as I kept over thinking why she didnt ask me more questions and why it was so quick and why she didnt approve our case on spot or why she didnt say our case is straight forward she will check and approve. (like other people talk about) So guys dont think too much as long as you have good case you should be fine. Good luck you all!
