The following U. Chicago Booth MBA interview report was submitted to Clear Admit by a Round 1 applicant. Good luck to them!
I met the interviewer in the admissions office after having lunch with another student. He was very friendly. We walked through my résumé, and he followed up with behavioral questions: tell me about a time when you had to deal with a coworker you disagreed with kind of stuff. He asked me why I was interested in Booth in particular and asked about what clubs/classes I was particularly interested in. He was definitely looking to see if I had done my research. At the end, we had time for me to ask him a few questions about the school, his experience, etc. We wrapped up by talking about next steps in the application process (essentially, waiting). The whole interview lasted about 45 minutes.
