Hello jeonacivil, and thanks for your post.
You have a solid profile – your stats are strong with a high GMAT and solid GPA’s, especially in your Master’s. And your work experience sounds impressive too, though you haven’t gone into too much detail, especially in terms of your accomplishments. However, as you know, the schools to which you applied are very competitive, especially for an overrepresented demographic. In Round 3, there are very few spots, so I would suggest that it is not worth applying in this round unless your profile is significantly above that school’s average. For example, these would be schools where the average GMAT score is below a 700.
Instead, and I know you mentioned the clock is ticking, but I would wait until Round 1 to apply to other top schools. You would have a better chance because it is the first round, and also importantly, you would give yourself time to improve your application. The fact that you were not invited to interview possibly illustrates that you have room for improvement in your application, perhaps in your resume and your essays, as well as your recommendation letters. You could also boost your extracurriculars. And you could spend the time before the Round 1 deadlines in engaging with the schools, to show them that each one is your top choice.
Good luck to you!
