Hello,
I was interviewed today (for the two-year program).
Some insights:
1) The whole interview was in English;
2) It last about 45-50 minutes;
3) The questions were the standard ones: Walkthrough your resume, some specific questions about the resume, Why Kellogg, What are your goals after the MBA, What will you bring to Kellogg;
4) Because during the answers I have broaden my response (talking about other subjects), I believe I had less questions (total of 6 or 7 during the whole interview);
5) My impression about the notes and the report to Kellogg (by the interviewer): it seems is not an evaluation, but just comments about some of the school principles. It was clear to me that, to highlight possible fit, he wrote every time I said something related to Kellogg values.
Best,
