By Caroline Diarte Edwards, Fortuna Admissions – the dream team of former admissions directors from the world’s top schools
If you’re preparing MBA applications, chances are you’ve already checked the obvious boxes: academics, test scores, work experience. What’s harder to assess is whether something in your application is sending the wrong signal – even if everything looks solid on paper.
In admissions committee discussions, applications rarely fall apart because of one dramatic error. More often, they stall because something doesn’t quite add up, or because the story is harder to advocate for than it should be.
Drawing on patterns we as former admissions directors saw year after year, here are seven mistakes that commonly undermine otherwise competitive applications – along with tips on how to avoid them.
Mistake #1: Telling an inconsistent story
Your essays, resume, short answers, and recommendations should work together as one narrative. When goals shift across components, leadership claims aren’t supported by evidence, or recommenders describe a version of you that doesn’t align with your essays, the file becomes harder to trust.
A useful test: after reading your full application, could someone describe you in one clear sentence? If not, the story likely isn’t holding together as it should.
How to avoid it
- Identify three or four core messages you want schools to remember about you.
- Check for contradictions in goals, timelines, scope of responsibility, and tone across all materials.
Mistake #2: Writing what you think the school wants to hear
Many applicants try to “perform” an ideal profile – smoothing out anything unconventional and shaping their story around what they assume admissions committees prefer. The result is often an application that is polished but emotionally flat.
Applications tend to land better when they focus on what is unique about you, rather than when you try to position yourself to fit into a particular mold.
How to avoid it
- Start with honest reflection about where you are coming from and where you are headed.
- Remember that it’s OK to be different; in fact it’s often the difference that can make you stand out.
- Keep your own voice; if your essays could belong to anyone with your job title, something essential is missing.
Mistake #3: Failing to tailor your application to the school
Admissions readers can immediately spot generic “Why this school?” answers. Listing a few courses, clubs, or famous professors rarely demonstrates fit on its own. More often, it suggests limited engagement beyond surface research.
Strong tailoring shows that you understand the school’s culture and learning model – and can explain why it genuinely aligns with your background and goals.
How to avoid it
- Go beyond the website by attending events and speaking with students or alumni.
- Connect specific program elements to your own goals and gaps, and explain why they matter.
- Apply to fewer schools if tailoring starts to become forced or superficial.
Mistake #4: Burying transferable skills in technical jargon
This is a real risk for candidates in technical roles. When resumes and essays default to acronyms, tools, and specialized language, readers struggle to understand the organizational impact. If the reader can’t quickly grasp what changed because you were there, it becomes harder for them to advocate for you.
This issue often shows up not because candidates lack leadership experience, but because they assume the complexity of their work will speak for itself. In business school admissions, it rarely does. Because of that, the solution isn’t to remove technical detail, but to “translate” it.
How to avoid it
- Lead with outcomes and decision-making responsibility.
- Use technical detail only where it essential necessary context.
- Write with a post-MBA recruiter in mind, because that’s how the admissions committee is thinking.
Mistake #5: Mistaking a common credential for a differentiator
A marquee employer or high-visibility project can be a strong foundation, but at top schools these profiles are often very common. When applicants rely too heavily on pedigree, their story can feel interchangeable. This mistake is easy to make because candidates don’t see the full applicant pool. Credentials that feel distinctive to you may be extremely familiar to admissions officers.
How to avoid it
- Highlight contributions that differentiate you from your peer group.
- Highlight moments that reveal your judgment, values, and growth.
- Get input from an experienced admissions professional on how your candidacy stacks up in the applicant pool for your target schools.
Mistake #6: Trying to say everything (and losing the plot)
Some applicants jam pack their applications: more achievements, more leadership examples, more everything. The result is often an application that feels busy and confusing rather than persuasive. When readers struggle to identify the core story, they also struggle to advocate for the candidate in committee. Focus helps others do that work for you.
Depth almost always beats breadth. A focused narrative with well-chosen examples is easier to remember – and easier for admissions committees to discuss.
How to avoid it
- Choose a clear through-line and let it guide what stays in and what gets cut.
- Prioritize the experiences that shaped you most.
Mistake #7: Outsourcing your application to AI
In recent cycles, admissions teams have noticed a rise in applications that are grammatically clean but strangely generic – flattened voice, predictable phrasing, and little lived specificity. If an application reads as interchangeable with that of another candidate, it won’t stand out for the right reasons.
AI can help tighten language, but it can’t replicate judgment, reflection, or lived experience. Overreliance on this tool often removes or obscures the very signals schools are looking for.
How to avoid it
- Use AI tools for support, not authorship.
- Do the thinking first, then refine.
- Double check your voice is coming through loud and clear.
Final Thoughts
Once applications move into committee discussion, the files that gain traction are often the ones that are easy to summarize and defend. They present a coherent story, a credible plan, and a candidate the school can picture contributing in the classroom and community.
Most application mistakes aren’t about a lack of ability, but misalignment – the gap between what the applicant intended to communicate and what the reader actually took away.
