Hi Aman,
Thank you for your note. I'll try to cover some of your questions below:
Given a variety of factors (e.g., nine years of work experience, already have an MBA, etc.), you should do absolutely everything you can to hit the high end of the GMAT range you articulated (and ideally exceed it, if you can). Especially for the programs you listed.
Some one-year programs have slightly higher average work experience levels than their two-year counterparts (e.g., Cornell Johnson), but you'll be at ~10 years of experience by the time you enroll. Given that you already have an MBA, you will have to make an extremely compelling case as to (a) why you need "another," and (b) why you need an MBA at this juncture of your career.
I'm not sure I follow the career goal you mentioned in your post ("moving from business to the corporate world") -- you will need to put a lot of thought and specificity into that goal, why and how a one-year MBA propels you toward it, and how an MBA and that goal are the next, logical steps in your career arc (which to this point has included five jobs in nine years).
I'd further recommend that you validate that any programs you're interested in allow candidates who already have an MBA to apply. Some programs do, some don't, and policies can change. In any case, conveying why you need "another" MBA will be critical.
Your GMAT result will have some impact on which programs you should consider. Again I'd try to maximize your score to the best extent you can. Once you know your score, I encourage you to identify one-year programs that align well with your profile, interests, scores, and work experience. For example, USC Marshall offers a one-year MBA for "mid-career professionals" with median work experience of 10 years.
Finally, I think trying to cram an entire MBA application process (let alone several) into 15 days is ill-advised. Focusing on getting as great a score as you can (even if you have to re-take the exam) and then applying in Round 2 seems more appropriate.
Kind Regards,
Greg
