Hey guys, thank you for all the good wishes.
Just did my Lauder interview a couple of hours ago. It was very casual, conversational and much different than a regular MBA interview. The questions were very focused on why the extra work of doing a dual-degree and how can Lauder help you in your professional ambitions. Another very important thing was to show that you already have multicultural academic/professional experiences in your life.
One important thing: it is a blind interview, they do not have access to your file, only to your CV and a couple of info that the adcom sends the interviewer.
Hope this helps future interviewees, specially those with off-campus!
