Employment Based Greencard

(Continuation of the below post).
The innterview was not as easy for me. The officer was polite; however asked many many questions, including confirmation of all my past addresses (5) which was kind of difficult, but i guess was ok for him to be as close as possible. He asked me about my job duties, my dad and mom professions and jobs, last entry date, all visas i ever had and passports, employment letter updated, and all the last questions on i-485. It was a good interview but maybe because he was too serious i got a bit nervous and saw jt hard; howver inside was ok because all my information is real and accurate. (he needed also copies of all documents he asked during the interview and i was prepared with them already which he appreciated: mostly birth cerrificate, passports and visas copies).
