Hi! Thanks for writing in. Your work experience appears to be strong. Even though you say you don't have many examples of leadership, you might want to consider looking for experiences where you took risks, showed initiative or made important decisions. Presenting anecdotes that highlight such things will show the AdCom that you have leadership potential - something they look for in MBA applicants.
In addition, your GMAT score is strong at a 710, though your quantitative part is just below the 80th percentile that many of the top schools look for in applicants. In pulling together your application, you might want to highlight the quantitative skills you use at work as well as those you've built through your education. That might help your case with the schools on your list right now, which are all very focused on strong GMAT quant scores.
Best of luck,
Rachel Beck
