Hi Aldermere, as you may have gathered from previous responses, it is a bit hard to know what they might ask as it all depends on context (and quite possibly level of funding, availability of staff/resources at that university). My interview was some time ago and it is all a bit vague now.
However, given a different faculty, context, country, and level of funding-I applied for fee and research costs scholarship but not living expenses-given this, they mainly:
* Wanted to go through my application and proposal briefly
* Wanted to check regarding my preferences for supervisors so they could assist with allocation
* Checked that I was the same person 'in person' as 'on paper' (including level of confidence and my understanding of the process)
* Checked that I had some background knowledge of my research topic and could discuss this in interview
* Wanted to know my reasons for applying for a doctorate
* Gave me an outline of the process to follow.
