University of Cambridge interview questions

A few days after applying for this position (through email), I was informed that my CV was interesting and the screening of the applicants (for the interview) will begin soon after the deadline. Three weeks later, I was informed that I was shortlisted for the interview and I was asked to confirm my availability for a personal interview. After confirming my availability, two weeks later, some material was shared with me to go through, to understand the nature of the proposed research project, that is to be held in a week.
