Adjustment of Status - I-485

Finally after long wait my interview is done today morning. It lasted about 15-20 min, I went inside with my wife & 2 months old daughter took an oath then he checked my file and asked if my I-130 is approved I said yes and then nicely he said I have to take only your interview for I-485 then we all went outside to drop my wife & daughter to the door and then me my lawyer went in his cabin again and interview started.
First he asked for my passport my EAD, I-94 & my DL after that he ask for medical which we have already submitted along with application and he found it then he wants me to verify my current address & day time phone number after that he said he will come to yes or no questions from I-485 application, he almost asked all the question from it and lastly he signed the I-485 application & also made me sign.
He did not asked for any kind of documents in short I did not open my file. The IO was nice, calm and very straight forward, lastly he gave me & my attorney a paper saying they will review my file and will send it to supervisor and will give their decision in 120 days.
