The Most Common Mistakes Indian Applicants Make in ISB Essays, and How to Avoid Them
ISB shortlists applications that have a GMAT in the 680 to 720 range over applications with a 740 when the writing is substantially stronger. I have seen this happen often enough that it is not an observation anymore, it is a pattern. The essays are doing more work in this application than most candidates realise. Strong ISB essays do more work in this application than most candidates realise.
Understanding what that means in practice requires starting with the actual questions, not a generalised view of what ISB is "looking for."

The ISB PGP Essay Questions for the 2027--28 Cycle
For the Class of 2028 (Round 2 deadline December 6, 2026; Round 3 deadline January 17, 2027), ISB has three essays.
Essay 1 (400 words, mandatory) asks, "What unique experiences have shaped who you are? What have these experiences taught you about leadership and the kind of leader you aspire to be?"
Essay 2 (400 words, mandatory) asks, "What intellectual experiences have influenced your approach to learning and have led you to pursue an MBA? Please describe using anecdotes from your own experiences."
Essay 3 (250 words, optional) asks, "Share with us any intellectual pursuits, unique perspectives, or experiences that you pursued that have shaped your worldview, your growth through these pursuits, and how they could potentially contribute to our learning community."
These three essays together are asking ISB to understand three things about you, who you are beyond your professional biography, how you think, and what you would add to their classroom. Every decision you make in the writing, what to include, what to cut, where to start, should be made in service of answering those three questions distinctly.
Why Most ISB Essays Miss the Mark
Before going essay by essay, there are structural mistakes that appear across all three prompts and account for most of what costs candidates the admit.
They write about work when the question asks about the person. ISB's first essay is not asking for another version of your resume narrative. "Unique experiences that shaped who you are" is a deliberately personal prompt. Candidates who answer it with a professional achievement sequence, led a team, managed a project, drove business outcomes, are answering the wrong question. The panel already has your resume. They want to understand what formed your thinking.
They describe events instead of processing them. Good essays do not summarise what happened. They show how the applicant made sense of what happened, the internal shift, the changed perspective, the recalibrated assumption. A candidate who writes "I led a cross-functional team during a merger and learned the importance of communication" is describing. A candidate who writes about the specific moment a silent disagreement between two colleagues collapsed a week of progress, and what that taught them about unspoken hierarchies, is processing. ISB wants the second type.
They write safe, consensus perspectives in Essay 2. The intellectual experiences prompt is asking about learning orientation, not about a list of books or courses. Candidates tend to either list credentials (did an online finance course, read about AI) or fall back on a conventional MBA rationale (wanted to understand business beyond my function). Neither is what the prompt is asking. ISB's own Dean has signalled that the programme wants people who "separate signal from noise and speak truth to power." The intellectual essay is where candidates can demonstrate that capacity, and most do not.
They treat Essay 3 as optional. It is optional in the sense that it is not penalised if missing. It is not optional in the sense that submitting it does not matter. In a close evaluation, a well-written Essay 3 adds a dimension to the candidate that Essays 1 and 2 cannot. Candidates who skip it are leaving space on the table.
Essay 1, What ISB Is Actually Evaluating
The question has three parts that most candidates collapse into one. "What unique experiences have shaped who you are" is the foundation. "What have these experiences taught you about leadership" is the translation. "The kind of leader you aspire to be" is the forward claim.
The most common mistake here is treating these as a sequence to fill rather than a layered argument to construct. The experiences do not need to be extraordinary. They need to be specific and genuinely formative. A childhood experience of navigating an economic crisis in the family, an early encounter with failure, an experience of being the only person in a room who saw the situation differently, these are often more revealing than a polished account of a corporate leadership achievement.
The leadership identity at the end of Essay 1 needs to feel earned, not asserted. If your experiences trace a pattern of how you build trust in adversarial environments, your leadership aspiration should connect directly to that. If it pivots to something unrelated to what you described, the essay has a structural break.
At 400 words, there is no room to develop three separate stories. One experience examined deeply, with genuine insight, performs far better than three experiences described at the surface.

Essay 2, the Intellectual Curiosity Test
This is the essay most candidates find hardest, because it asks about learning orientation rather than professional achievement, and most applicants have not been asked to think about how they learn before.
The key word in the prompt is "approach to learning." ISB is not asking which intellectual experiences you have had. They are asking how those experiences changed the way you process information, engage with problems, or make decisions.
The MBA motivation must emerge from this narrative, not be bolted onto it. If your intellectual experiences show that you have been operating at the intersection of business and technology without the structural language to synthesise them, the MBA rationale should connect to that specific gap. A generic "the MBA will help me accelerate my career" closing is a signal that the applicant has not thought through their own argument.
The "anecdotes from your own experiences" instruction is telling. ISB does not want abstraction. They want a real moment, a project that rewired how you approach ambiguity, a failure that restructured your mental model of how businesses work, a conversation that changed how you evaluate risk. Specific and personal, not broad and theoretical.
Essay 3, Why You Should Write It
The optional essay asks about intellectual pursuits, worldview, and contribution to the learning community. In practice, it asks what the mandatory essays could not contain.
Used strategically, it is the place for the dimension of you that does not fit neatly into the leadership or learning narrative, an academic interest, a cultural perspective, a non-professional engagement that has shaped how you see the world. Candidates who bring a genuinely distinct worldview perspective in Essay 3 tend to stand out in holistic review precisely because it signals range beyond the professional record.
The 250-word limit makes it tight. Every sentence needs to be earning its place. The community contribution angle is worth taking seriously, what specifically would you bring to a classroom discussion, a case study, a peer group?
The Reapplicant Essay
For candidates applying again, ISB requires an additional 200-word essay addressing what has changed since the last application. This essay is often underestimated. The most costly reapplicant mistake is treating it as a formality or submitting a slightly updated version of the previous application.
What the panel is evaluating is whether the candidate used the time between applications purposefully. A meaningful update, a promotion with expanded scope, a GMAT retake that reflects genuine improvement, a developed clarity on goals, is substantively different from minor cosmetic changes.
One Number That Matters More Than You Think
ISB's Class of 2026 data shows that the average GMAT Classic for admits was 720, with the range spanning 640 to 780. That 640 at the lower end did not get in despite a low score. They got in because something in their application, the work impact, the essay quality, or both, compensated convincingly. Over 17 years and 500 plus admits, I have consistently seen that the essay is the primary compensating factor for profiles that carry a score or experience gap. It is also the differentiating factor between two applicants with virtually identical numbers.

What Our ISB Admits Did Differently With Their Essays
Saumya Tandon, a software developer with three years of experience, applied only to ISB with a 665 on the GMAT Focus Edition. She spent two months on essays built on genuine introspection and joined the ISB PGP Class of 2026.
Samarth Bhatt, a Deloitte consultant, traced his first rejection to one cause, a goals essay that was the weakest link in the application. On reapplication he converted ISB PGP with a 50 percent merit scholarship.
Tanu Poddar and Shivam Goenka, a Chartered Accountant and a finance professional, both converted ISB PGP. Their shared advice is that the optional essay is never truly optional, and that essay introspection took them longer than GMAT preparation.
Aaditya Veer Sharma went through six essay drafts and seven mock interviews before his ISB admit. More admit experiences are on the GOALisB reviews page.
