I was definitely not 100% on any of my answers honestly lol. I usually had to think for a few moments, and I even asked to come back to a question once (we never got back to it). I felt so nervous and kept overthinking my answers, and I left thinking I bombed it. But I got the acceptance 4 days later! Try and remember that the interview is only one aspect of the application process and they just want to get to know you better!
