Hi,
We have helped many people override low GMAT scores (in the mid- to high-600s) to gain admission to HBS, but that is exactly what happened - they "overrode" what potentially could have been a deal-breaker. Whether that sort of "override" is possible is often dependent on the whole story. What is a candidate's backstory? What is their profile? What are their professional achievements? And, of course, the application should be outstanding (recommendations and essay) to maximize odds of overriding a low GMAT score.
In general, you should strive to get your score in the 700s. We at
MBA Admit.com have found in recent years that 720 is safe, 710 is acceptable but soft, 700 can be acceptable depending on the profile, and 730 and above usually means the GMAT was not a reason for a rejection. (Indian foreign national men often have to hit a higher number, like 750...)
Best wishes,
Dr. Shel
