i'll kick this off - i know that i got a lot out of looking at the profiles of admitted students from previous years:
-admitted in round 1
-military applicant with a "public ivy" education and humanities degree (~3.7 GPA)
-submitted my GRE score, as my GMAT was pretty terrible (my GRE equated to about a ~740 on the GMAT, although I know it's not the same thing)
-28 years old
-no real strong extracurriculars, but i was able to emphasize my leadership in the military, so i think it balanced out
i had my interview over Skype. most of my questions centered on my experience in college and my current job.
hope this helps other applicants! looking to meeting everyone next fall
