Hi,
That's an outstanding score you have got. I must say that it sets you apart from the crowd at least on one criteria, that is, academic performance. Your GPA is above average too. But, that's just one part of the application.
As you have just graduated from undergrad school, you still have at least 3 years to build a solid application for the top 10 business school. Business schools evaluate applications based on other criteria as well. A solid GMAT score is a hygiene factor, but you should have at least one thing that sets you apart from the crowd.
Over the coming years, look out to have a good work experience which I am sure you would be able to do as you have offer from the boutique management consulting firm. Remember leadership is the key.
You need to have strong extracurricular activities too. Select one thing you are truly passionate about outside your work environment, and do your best at that. Be it sports, community service, start up, music etc. Top business schools look for students who can add to their legacy. You should have substance to convey that you certainly can.
Your work experience and your extracurricular activities help you write excellent application essays which are an important aspect of your application.
Good Luck!
