Interview Help - Prospective Student - Aero

Hey!
I just got my interview today and I wanted advice. Anything y'all say is appreciated!
I'm (international) applying to MEng Aero.
Can you please give me an idea of what kind of questions they'll ask?
Will it be formal or more like oxbridge leaning slightly on the conversational side?
What is the difficulty level of the question they ask us to solve, and will it be physics or maths?
How much do they ask about activities from the personal statement?
My interviewer is Dr. Masoud Seifikar (if that helps)
