The group interview had 7 students, and people were friendly, but a bit aggressive in making sure they had speaking time (which was different compared to the multiple mocks I did). The follow up 1:1 interview was with a 2nd year who asked about what I learned from the group interview, any application updates, what I look forward to doing at Wharton, and about my goals. The 2nd year was quite friendly, and this portion felt very conversational.
