Hello kiseki, thanks for your question.
I am not a career counselor, per se, but I will comment broadly!
Leaving aside all considerations about what other people think, it really just comes down to whether you need an MBA to achieve your career goals? If you want to attend business school, you will need to demonstrate to the admissions committees that your desired career path necessitates an MBA. And, this means specifically, not just needing leadership and management skills. Anyone could say that, and we could all use better skills in those arenas.
So, if you can achieve your goals without business school, then go forth and pursue them. If you truly need an MBA, then that should be your main motivation for applying.
Your competitiveness will come down to the quality of your leadership experience to date in and out of the office. Can you draw upon “moments” when you truly led: influenced individuals and organizations, drove results, took initiative?
Finally, it will also depend on your GMAT score. I don’t put much stock in practice scores; they can be off in either direction.
Best of luck!
Brian
