Everyone,
Would you please help me to evaluate my profile?
I am a 31 years old first generation Korean American. To me English is my second language.
Undergrad: Accounting major with 3.43 GPA from public University
GMAT: 690 (M 50, V 33) AWA 4.0 IR 1

(my previous score was 640 with AWA 5.0 and IR 6.. not sure what happened to me on the exam day)
WE: Big 4 accounting firm : audit function in US office 3.5 years (CPA)
Same firm in Vietnam: business development function for 2.5 years
Social networking startup: co-founder for 5 months (not going too well)
Goal after MBA (in the order of preferences): 1. try another startup 2. work for other startups or more established IT companies such as Google 3. work for VC.
Target schools: HBS, Sloan, Stanford, Haas (other than these schools, I heard that Babson is known for its entrepreneurship program. I want to know how advantageous Babson MBA is to me considering ROI, etc.)
I have already applied to few schools and was dinged from HBS and Booth and waiting on few others, but losing confidence as time goes by.
I would highly appreciate everyone's comments on areas of improvement (such as I MUST re-take GMAT and increase especially IR score, etc.), better matching schools, career advises, etc.
Thanks all. Cheers.
