Nobody here would know exactly how your second interview will go. I am only suggesting to prepare for the worst scenario and hope it goes a lot easier than this. If you prepare for tough interview, you will have answers for any scenario.
As to my knowledge, no I don't work in the field, but immigration is my passion.
I've read thousands of pages on Visa Journey and other immigration related websites on various subjects, including visas, adjustment of status, removal of conditions, naturalization over the last 7-8 years. I contributed with close to 13000 posts on Visa Journey since 2022 when I joined it. I watched every single episode of Immigration Answers Show on YouTube, which is about 1000 hours of content, questions and answers by attorney. I also watched other attorneys, perhaps 200-300hrs additionally. I read USCIS manual, watch updates on immigration, review forms regularly. And lastly, I went from various visas to becoming a citizen myself. I have few friends who went through this process to. This is where I'm coming from. By no means my messages here are the ultimate truth or legal advice.
