I attended my interview on Friday afternoon. It was a relaxed and informal session, in total just under 25 minutes. The questions I fielded were straight forward: give a self-introduction, explain a bit about the future of my industry, why CEIBS/why full-time MBA, where else have you applied and how do you plan to pay for the program. Both interviewers were professional and did not provide much feedback. I was given an opportunity to ask questions, but I did not have anything in specific that I needed to address.
I spoke at length with the candidate who interviewed immediately before me and his experience was similar. Hope it turns out well!
