There are differences between your examiners, but it might be more useful to focus on what they have in common than what separates them. They’re both academics, both experienced, both prepared.
They’ve both read your thesis, both thought about your viva in advance. Now they’re ready to ask questions, steer discussions and listen to what you have to say.
You can’t know everything they will ask, say or do in advance. Instead, use a little time to look at who they are and what they’ve done. Get a sense of what might motivate their questions and their approach to your viva.
