What's worse than a death sentence? Being kept on your school waitlist.
Read what Jeremy Shinewald, Founder/President of mbaMission has to say about responding to "Waitlist":
In recent weeks, many candidates have received responses from MBA Admissions Committees that can be even more frustrating than rejections: “You have been placed on the waitlist.” So, what do you do when your status is uncertain? First and foremost, listen to the Admissions Committee. If the AdCom tells you not to send follow-up material of any sort, then you should not yield to temptation and send material you think will bolster your case (bold emphasized). If you (misguidedly) choose to send additional information when it has not been requested—and especially when the AdCom has asked you not to—you will definitely identify yourself in a negative way—not the type of message you want to send to the group that will be determining your fate.
Still, some schools will ask that you provide additional information. In this case, you may also experience some frustration: “What can I offer the MBA Admissions Committee as an update? I submitted my application three months ago!” You can start by explaining (if applicable) that you have been targeting certain weaknesses—retaking the GMAT and increasing your score, for example, or taking a supplemental math class and earning an A grade. Further, if you have any concrete news regarding work promotions or the assumption of additional responsibilities in the community, you should definitely update the MBA Admissions Committee on these points.
Even if you do not have these sorts of tangible accomplishments, you should have some news to share. If you have undertaken any additional networking or completed a class visit since the application deadline, you can offer a window into your burgeoning interest in the school. (When you are on a waitlist, the MBA AdCom wants to see evidence that you are passionately committed to the school.) Further, even if you have not been promoted, you can creatively reflect on a new project that you have started working on and identify the new professional skills/exposure this project has provided (for example, managing people off-site for the first time or executing with greater independence). Finally, the personal realm is not “off limits,” so you should also feel free to discuss any accomplishments, from advancing in your study of a language to visiting a new country to completing a marathon (just as examples).
With some thought and creativity, you should be able to craft a concise but powerful letter, showing your recent professional and personal growth, while expressing your sincere and ever increasing interest in the school—all of which will serve to increase your chances of gaining admission.
