Hello again
As I said before, your work experience is quite impressive as it has many elements that highlight your leadership and analytical skills. While writing your essays, you should discuss how you went up the ladder in a relatively short period of time, outperforming your peers and how this transformed your responsibilities from a team member to a team lead to handling crucial decision making roles. You should draw the adcoms attention to the multitude of experience that you have gained in every strata of your firm and how much you would have to offer to the school's MBA class.
Discuss your experiences with the CXOs and the impact your solutions had on your clients' firms - how effective and efficient they were. Were you involved in any extracurricular activities at your firm, outside of it or during college? Mentioning ECs from your school days is not advisable. If you have not been part of anything so far I would advise you to involve yourself in some activities so as to present a near perfect application which is sound in all fronts.
You should also discuss the experiences you have had working with global teams. (You should also mention how effective you have been as a team player throughout your career as it is important to a few business schools such as Kellogg.) This combined with travel abroad must have given you substantial international exposure (though it is never a requirement but will certainly add more value to your profile) to your profile which will be appreciated by business schools' adcoms.
It is very important that you have clear post - MBA goals. You need not have a business plan but you certainly need to have a clear idea of the field you want to pursue after MBA, why that field interests you and how would an MBA from that business school help you meet your goals. Going up the hierarchy and to attain a more central managerial role in your firm could be a good reason to pursue MBA. Of course you will have to present a convincing case for yourself.
If you want to continue in consulting you can take a look at these schools (based on how good the school is for consulting)
Ambitious: Kellogg, INSEAD, LBS, MIT Sloan and Wharton
Modest: Dartmouth - Tuck, Michigan - Ross, Virginia - Darden, Duke - Fuqua
Safe: Emory - Goizueta, Oxford - Said, Cornell - Johnson, Carnegie Mellon - Tepper, UT - Austin, Indiana - Kelley
You can also consider these schools - HBS, Chicago - Booth, UCB - Haas, Yale, Columbia, NYU - Stern.
I would advise you to focus on GMAT prep and getting involved in additional activities.
Hope this helps
All the best
