I was fortunate enough to be accepted into HBS in Round 2 and will be heading there this Fall. I have never done an Q&A on this site before and I feel that now might be a good time to do so. I hope that sharing my experience with the MBA application process might be somewhat useful to the WSO community.
Education: AB from Harvard (Economics)
GMAT: 730 (HBS median, e.g. nothing special)
GPA: Slightly below HBS median (never came up during the interview as an issue)
