Hello
Assuming you are aiming for top schools then a score above 700 is desirable. A higher GMAT score is advisable if you are aiming for top institutes abroad. Also the GMAT alone won’t determine your chances of admission; your work experience plays a vital role as well. You need to ensure that academically you are in a good position. However it is not just the academics but beyond the academics that will help you in determining your candidature.
Do highlight your work experience to tell what you did there like-what were your achievements, what initiative you took, what changes you drove in your workplace etc. So if you can show that in terms of work that you have demonstrated the skills business schools are looking for you could still put in a strong set of essays.
Also make sure in your work what you did there like-what were your achievements, what initiative you took, what changes you drove in your workplace etc are exhibited well in your application.
Make sure you follow the ‘show rather than tell’ principle so that the admissions committee could really understand your strengths and differentiating factors.”
