If you want your application essays to succeed, make sure to avoid the following mistakes:
1. Don’t mess with the truth
Don’t stretch, twist, or otherwise change the facts. Admissions officers and essay readers are paid to sniff out overblown claims and unconvincing use of evidence.
2. Don’t suck up
Don’t talk about the reputation of the university, wisdom of the faculty, beauty of grounds, |size of endowment, power of alumni network, etc. Talk about the benefit you will add.
3. Don't make excuses
Don’t excuse weak grades, poor GMAT, lack of volunteering, job-hopping, etc. It focuses the eye where you don’t want it. If you have a fix, state it. Otherwise just move on.
4. Don’t try to be someone else
It’s natural to want to fit in with the business school type, but business schools seek a broad mix of backgrounds and experiences and opinions. Be who you are. It’s enough.
5. Don’t be generic
You must differentiate yourself in a valuable way. When is a statement generic? If it could come up in the next person’s file. If it could only have been said by you, it’s specific.
6. Don’t stereotype yourself
Force the reader to go beyond the stereotypes of background, ethnicity and job definition that may be associated with your profile, to reach the layer where you are unique.
7. Don’t try to be over-competent
Not only is nobody perfect, but as an MBA student-to-be you are by definition still a work in progress. Be upfront about what you still need to learn.
8. Don’t repeat material presented elsewhere
The reader will have your complete file, so any repetition of its contents in the essays is a waste. If you want to highlight a point, take care to reframe or cast a new light on it.
9. Don’t try to say too much
It is better to focus on a small piece of your story and chew it thoroughly than to bite off too much and choke on it. Narrow your horizons but deepen your analysis.
