Is it worth applying to HBS in round 3?
GMAT: 760, Q50, V42; GPA: 3.5; WE: 42 months consulting; New York
Hard to say without knowing more about your profile. I spoke about this with my consultant and he told me that they reserve some slots in R3, but it's usually for candidates from unique backgrounds that normally wouldn't apply to B school or superstars that couldn't apply earlier.
Your GMAT is great, GPA is ok, not great, and you're a consultant. I'd imagine they've already culled through hundreds of consultants apps and hired the top 10% or so across the world and they probably don't have too many more slots for those types unless you're an absolute superstar.
Apply if you want but your chances are very low, as are most anyone who applies r3. I'd wait for next year.
