Typical format: Opening question is typically underarm bowling, eg what did you find the most interesting or important part of your theses? Then we chug through from the start page by page and each examiner asks questions that occurred to them while having read it. Nearly all theses have typos etc

so some amount of corrections is almost inevitable. Anyway I don’t know how much of this transfers to your subject/uni but I hope it helps 😊 And if your social media is any guide, you will be very, very good at thoughtful & incisive commentary so I’d bet on a barnstorming viva 😁
