I have your story about your application process but I am missing the detail about you to really be able to advise you on what you should do (for example, whether you should wait one more year, retake your GMAT, moderate you school choice or whatever!).
Basically I need more info - your undergraduate school, major, grades, your GMAT (and TOEFL if relevant), info about where you worked, what you did, what your achievements are, how many promotions you got, what managerial experience you have, what community service, what extra curriculars, etc. etc.
Also, although I believe what you say about your essays, I can;t really tell you how to change them, until I actually see them.
So maybe start by posting more detail about YOU, and then we can take it from there.
If you like the post, give it a KUDOS!
