I have an interview for my Dhil in Management Studies at Oxford. Can anyone please tell me the scope of the interview and what is normally asked in these sesson?

Even I am getting ready for an interview on Monday (different place). I have 2 decades of industry experience and expecting committee to really know about my motivation to do PhD. Beyond, I am getting ready if I could take rigor and length of program (5 years!!). Why specific college and why Management studies could be common questions. Additionally, i am getting ready with more details about specific subject that i have proposed in SoP.

My best wishes for your preparation.
