You have a decent profile with good international work exposure and GMAT Score.
As you must be knowing that the average work experience of most of the business school is 4-5 years and since you have 8 years of work experience you have to justify comparatively more on your application.
It is highly advisable in your case to focus on your application evaluation essays. This is where you can demonstrate your leadership qualities, achievements, professional vision and other abilities. A well presented and perfectly written essay is absolutely critical to make a strong case for yourself during the final interview and more so when you have an average GMAT scores.
I would strongly recommend you to seek assistance from professional consultants for guidance who can more closely review your situation and provide you with a list of B-Schools where you would have chances of converting your application to admission. You should also get your essays reviewed from them before sending it along with your application to better your prospects. You may also visit http://bit.ly/1bxgRzX
