Employment Based Greencard

Here's our interview experience. The whole process took around a hour but the actual interview was just for 20 mins. We were given the oath to begin with and asked to sign the attorney waiver form since we didn't take an attorney.
The IO went through the details in the I-485 basically checking all the information inside it and going through a selected number of 'yes/no' questions. My wife was also asked to confirm the details in her I-485 document. No questions regarding job responsibility. We were then asked to sign the section of the I-485 to indicate that we appeared for the interview. The IO asked for the employment verification letter,latest paystubs, W-2's & tax documents and asked if we had any additional documents to submit. We ourselves gave our joint bank statements as well as our marriage certificate. The IO mentioned that rest of the documents look good and that our attorney will get a mail if there are additional documents needed. Overall our interview went great.
