5. Mount an influence campaign
I would only recommend this if you (1) truly need to be admitted to one particular business school in one particular cycle and (2) you are comfortable taking on the social capital debt of such a favor.
The people who make up admissions committees are social animals like the rest of us and can be influenced by others. Specifically two types of people: VIPs with opinions that the Adcom would respect (e.g. famous CEOs, political leaders, and prospective donors with whom the school is trying to curry favor), and current students whom can vouch for your “fit” at the school.
When it comes to VIPs, either you have one or you don’t. Personal/family connections are often too weak to be meaningful, and the waitlist timeline is usually too short to develop a good relationship with a VIP from a cold start.
When it comes to current students, start by looking at your network on LinkedIn and see who is currently at your target school. Look for shared connections such as employer, undergrad, or high school. If you find someone you know well, explain your situation and see if they are willing to vouch for your fit at the school to the Adcom, using your new awesome narrative (see point #1).
6. Be humble, be positive, be patient
Showing any sign of frustration with your situation is absolutely lethal to your application. Often, admissions deans are just itching to find reasons they can remove people from the waitlist – don’t give them one. Remember: you are the happy warrior, and the waitlist is a marathon, not a sprint.
7. Worst case scenario: use the lessons of the waitlist to make a better application next time.
Many schools look favorably on re-applicants and the classrooms are full of them. Next time, hire us the first time and we will make sure that you put your best foot forward.
