Hi there,
More than happy to share!
As I said when I started this thread, the interview was split across two days. It started with a mingling session with the current phd students (and we got to ask all sorts of useful questions), then an introductory lecture and question period with the course head, then we were taken on tours across all the facilities that were relevant (and got to ask questions about those as we went), then we had a few hours break in our hotel before dinner with some of the current PhD students and some of the faculty staff (more questions time + wine).
The next day we had the formal interview, which only lasted half an hour. On the whole the questions they asked were very much tailored to my own application, my experiences, my achievements, my academic and work background. From what I heard each interview was mapped out with the applicant in mind. For instance, the technical questions they asked me were relevant to me, not necessarily to the PhD - my technical questions were focused on research design and behavioural neuroscience because my background is in psychology and clinical neuropsychology, whereas the person before me was asked about theories in neurochemistry because that was more related to hers. They are aware that neuroscience is a heavily interdisciplinary area and that the people applying will not have the same base knowledge as one another.
Otherwise, my background is not what I would call biological. I haven't studied straight biology since GCSE, but I did work in a neurorehab unit for a year (as an assistant psychologist) and my final year modules were all heavily focused on neuropsychology, which has some obvious crossover.
If you have any more questions feel free to ask! If not then good luck with your application!
