2nd Round 1Y Applicant here.
Had my alumni interview today. Interviewer had clearly examined my resume because he began by asking me specifics about all of my experiences. He asked me my career goals and asked me how I planned to accomplish it. He then probed further and asked what exactly I could do at Kellogg to accomplish my goals without stating the obvious in taking interesting classes. Although I didn't get asked Why MBA? why Kellogg directly, those questions were more or less answered throughout our conversation.
My experience felt more like a job interview than a bschool interview. I was prepared for this as a friend of mine who had his Kellogg earlier had a similar experience. Overall, the interview was positive and was told that I would be a good fit for Kellogg. Alum said Kellogg was special place and that he had an amazing experience.
Now its just wait and see for at least 1.5months? Good luck everyone
