Very simple interview process. We arrived about 15 minutes early and they called us for the interview right on time. Our interviewer was very friendly and nice. She asked us to verify our information like our address, my husband's occupation (he is the beneficiary), and asked him some of the background questions again that were part of the AOS application. She didn't ask us anything specific about our relationship or for any updates on my finances as a sponsor. We had already submitted a lot of background info, so she only asked for documents proving shared residence. We submitted a copy of our rental lease (both names), rental insurance (both names), and various bills under each of our names at the same address. Then, she told us she was approving our application and we should have the card in the mail within a few weeks. The process was very painless and pleasant.
