Nice score. But B Schools optimise for diversity as they want to build the best possible class experience. Indian Males in It/Tech companies are over representated, so average GMAT scores of top B Schools are not what you’re up against.
You’re up against Indian Males in IT/Tech companies which skews a little higher. Although, according to me 770 beats that healthily.
You should try for INSEAD/LSE/LBS as well. Apply to T15 as well. You haven’t mentioned a lot about your WorkEx but if you’ve shown that you have grown in one organisation with multiple promotions then it looks very favourable over switching jobs.
I’m going to be honest. Your GMAT is good but your Acads and work ex look weak. You’re likely to be rejected by HBS, Stanford, Kellog etc.
The truth is you don’t need a perfect score to get into a top B School. You need a compelling story. The AdCom needs to feel that you are on track to change the world and are a high potential individual.
Your profile doesn’t scream any of that.
