I hate to discourage you, but I have to say it is much more difficult to get into a top B-school than a top global company. I can't understand why so many people focus only on Harvard or top schools. Most Chinese applicants have brilliant achievements and compelling GMAT scores. How do you surpass them if you have no working experience. Graduating from top 10 schools in China means nothing. Hundreds of applicants graduated from top 5 schools with excellent GPA.
Moreover, the more experience you have, the more you will learn from a MBA program.
