Candidates give a lot of focus to time in the viva. How long could it be? How short might it be? What do they feel like?
My four hours felt very short. The short break afterwards felt very long. Many graduates have told me similar stories over the years; however long their viva was, it felt like it flew by.
It’s useful to be aware of stories and expectations, but how long a viva is doesn’t really matter for the most part. You won’t know how long it will feel like until you’re there.
Rather than focus on how long it will be or will feel like, it’s better to focus on what you will do in the viva.
How will you respond to questions? What will you take with you? How do you want to engage with your examiners?
