Admissions committees look for a variety of factors beyond just work experience, such as academic performance, leadership potential, extracurricular activities, and overall fit with the program.
If you can demonstrate your achievements, leadership potential, and impact on the organization in your application, and show how an MBA will help you achieve your career goals, you may still be a competitive candidate for top MBA programs.
However, it's important to note that work experience is just one factor in the admissions process. Admissions committees will also consider the quality of your work experience, the industry you work in, your undergraduate institution, your GMAT/GRE score, your essays, your letters of recommendation, and other factors. So it's important to focus on presenting a strong overall application, rather than getting too hung up on any one particular aspect of your background.
