Just had my interview yesterday on campus with 2nd year student. Pretty conversational overall and it took me 1 hour.
Questions from what I remember were what you have already read online from GMATClub reports and Clearadmit:
Walk through resume.
Why MBA/why now?
Why McCombs?
Example of leadership experience.
Example of conflict at work and how it was resolved.
Short term long goals and long term goals. What about Plan B?
What did you learn through application process?
Experience with diverse group?
What would you contribute at McCombs?
Questions for him.
Also, decided to go for the lunch and learn they had on campus for that day. Had a nice chat with a couple of 1st year students there. Now to wait for December. Good luck to all!
