Hi Nitesh,
Thank you very much for your note. You've shared a lot of information, and I'd be happy to connect by phone or Skype to walk through those and others in greater detail. We'll be able to cover a lot more ground, with a lot more nuance, by connecting directly. If that sounds helpful to you, please feel free to email me at greg[at]avantiprep[dot]com and we can aim to set up a time!
In the meantime, two challenges I observe regarding your potential candidacy are (1) your current GMAT score and (2) the fact that you already have an MBA. Your current GMAT score unfortunately falls well below the average for the three U.S. programs you've listed. Those programs are ultra-competitive, and applying with your current score would be extremely challenging.
While your score is a little closer to the average at LBS and INSEAD, I do believe it would be in your interest to retake the exam and improve your score (especially given the caliber of programs you've listed). And while I understand the appeal of the most elite schools, I also believe it would be in your interest to broaden your list of target programs. Happy to elaborate if we chat.
Finally, while a number of programs are open to the possibility of "second MBAs," already having one only raises the already high bar for you, as an applicant, to articulate why you need an MBA. (In your case, you'd have to credibly articulate why you need a "second MBA."). Given your current GMAT score and the fact that you already have an MBA, thorough program research and smart, strategic school selection will be of heightened importance. Improving your GMAT score -- however challenging amidst competing work/life priorities -- would be an very valuable first step!
Best Regards,
Greg
