University of Cambridge interview questions

There was only one interview that took around 30 minutes. It was conducted online. There were three professors from the department present that each asked a couple of questions. It was quite laid back and there was no hard drilling on the science, they just wanted to know more about my intentions and reasons for applying.

POIs asked research questions and related math questions. First introduce myself then they ask questions about my research, then they ask questions about their own research, finally they ask me questions about mathematical background.
