Age: 26
Background: Female, Indian, born and brought up in Saudi Arabia,
Educational Background: UToronto 3.1 (Accounting and Economics), Wilfrid Laurier University 3.85 (Masters in Business Economics)
Professional Work Experience: one year in start up consulting company in Dubai as Business Analyst\Team lead for few small projects
Post Masters: 3 YRS Analyst-Associate (one promotion) at Mid Size consulting firm (Economic Consulting) in Toronto

Part time Work Experience: During UnderGrad PT Financial Assistant at University Dept, Research Assistant at Econ University Dept., Summer Analyst at Indian Transportation firm, Summer Analyst at Deloitte Saudi Arabia, during Masters TA for Econ Course, summer internship at government agency
GMAT:720 on practice tests, aiming for 750 (might be a stretch)
ECs: very involved in undergrad and grad (everything from student government, student center finance committee, Club VP etc). currently volunteering weekly at community center - mentoring children, running activities etc. Interests are foods blogs, fitness etc.

I might want to focus (in my essays) on my background (no money, came to Canada at 17 with no financial\parental support, attended large university with no guidance). Epiphany I had the year after graduation really put me on track in life. I realized that during my undergrad and the horrible experience I had I had not one single ambition or dream. Post undergrad became very very determined and ambition.

Post MBA aspirations:

Would love to work on management consulting or in Corporate Strategy at a large MNC for 5-10 years before I start my own company.

Strengths: Good GMAT Score and Masters GPA. Lots of PT work as well ECs. Worked in India, Dubai, Saudi Arabia and Canada?? Maybe Strength.
Weakness: 4 Years of Total work experience and only one promotion at current place (in my three yrs here)

Given all this could you help me figure out a list of stretches, sweet spots and back ups. I'm open to moving to the States or Europe.
At this point I'm open to suggestions. Ofcourse I would like to aim for the best but I'm realistic at the same time.

Thanks in advance!
