ISB Admission FAQs: A Re-Applicant's Complete Q&A on Cracking ISB the Second Time
- Jul 20
- 10 min read
Is ISB open to reapplicants?
Mayur is a mechanical engineer with four and a half years of experience in data analytics. He worked across sales and procurement functions at a global compressor manufacturer, and currently works with an IT services organization based out of Pune, supporting a US healthcare client, where his role centers on client interaction, requirement gathering, and building analytics solutions or automations to fix process inefficiencies.
He is also an ISB re-applicant. His first attempt was rejected. His second attempt, prepared in just six to seven days before the deadline, converted into an admit. Below is his complete story, broken into the specific questions applicants actually ask, answered directly from his own account.

What is your professional background, and what triggered your ISB MBA decision?
Mayur has spent close to five years in data analytics. In his previous organization, a global compressor manufacturer, he worked across sales and procurement domains. He currently works with an IT services firm on a US healthcare account, where his job involves interacting with clients, understanding their requirements, and building analytics solutions or automations to address process inefficiencies.
He is a mechanical engineer by graduation (2021). The idea of an MBA had been present since his graduation years, though not fully formed. It sharpened once he joined his current role as a data analyst in a client-facing position. Watching his manager and business-side colleagues in client discussions, he noticed how business decisions, even small ones, rippled out to affect broader outcomes and people, while his own role stayed focused on technical delivery. That exposure convinced him an MBA would be a natural extension of his current job: retaining the technical mindset while adding a business layer on top.
How did you prepare for the GMAT for ISB admission, especially coming from a CAT background?
Mayur had a CAT percentile in the 94-95 range from an earlier attempt at that exam. Rather than starting GMAT prep from scratch, he leveraged that base directly, reasoning that a good score, once achieved, would stay valid for a couple of years regardless of which exam it came from.
His preparation strategy had a few explicit rules:
Identify weak areas early. For Mayur, verbal was the weaker section, so he focused more effort there.
Never leave any topic as "optional." Skipping a topic to save time risks losing an easy question if one happens to come from exactly that area.
Cover the full syllabus rather than betting on partial preparation.
Take mocks, but treat the number of mocks as far less important than the depth of analysis after each one, specifically identifying where he was slow, where he made silly mistakes, and why.
Stay calm on the actual exam day so preparation can translate into performance without anxiety interference.
How long should GMAT preparation for ISB admission take if you're building on a CAT score?
Mayur's guidance splits by starting point:
If you already have a strong base, similar to his own CAT percentile, three to four months of focused GMAT preparation is enough.
If you are starting completely fresh, seven to eight months is a more realistic timeline. He suggested spending the first three to four months on sectional mocks and syllabus coverage, then dedicating the final two to three months to full-length mock analysis, specifically reviewing where errors are occurring.
What is the hardest part of the ISB reapplicant journey, even with a strong GMAT score?
For Mayur, the hardest part wasn't the GMAT itself. It was that he was a re-applicant. Having failed to get in on his first attempt, his confidence took a direct hit heading into the second attempt, he wasn't sure whether the outcome would be any different the second time.
To work through that, he sat down and literally wrote out what had gone wrong the first time, in his essays and in his interview, point by point rather than as a vague sense of failure.
Once that diagnostic was done, he described building the actual application as the next major difficulty: candidates often exaggerate their achievements or underplay them, and finding the exact balance, a genuine profile that still clearly shows strong points to the school, was the most difficult and most important part of the rebuild.
What went wrong in the first ISB interview attempt, and how should a reapplicant change their approach?
Mayur was direct about this. Reflecting on his previous application's interview, he identified his main mistake as trying to impress the interviewers rather than being genuine. That approach did not work.
For his second attempt, he was adamant about having a genuine, candid conversation instead, deciding in advance that he would not exaggerate or bluff about anything, reasoning that experienced panelists will catch it if a candidate tries to oversell.
To prepare for this shift, he went through roughly five mock interviews within a month. These mocks specifically helped him with a separate, more mechanical problem he'd been struggling with: the length of his answers, some too short, some stretched too long. The mocks also prepared him for pressure, because his actual second-attempt interview turned into a full grilling session rather than a conversation. He credited the mock preparation with helping him hold his nerve through that pressure.
What does ISB admission result day actually feel like for a reapplicant?
In the six to seven days leading up to the result, Mayur tried to stay detached, telling himself the outcome didn't matter and that he was calm regardless. That composure held until the date got closer, around the 25th or 26th of November, when his heart rate started climbing.
He also began receiving calls from other applicants who had applied alongside him, asking whether he'd heard anything yet, updates on who had gotten offers and who had been rejected. That added to the tension.
When his own result came through, the dominant feeling was a mix of happiness and relief, relief specifically, because the entire process had been genuinely hectic, and no one else can fully judge your own case the way you can.
What can ISB essays and interview prep teach you about yourself as a reapplicant?
Two specific things. First, he learned how to frame his work experience so it aligned with the actual values of the school he was applying to, understanding, now that he's part of the ISB community, what kind of people and profiles the school tends to select, and shaping his narrative to showcase that alignment.
Second, during interview prep, he was given a set of roughly 25 to 30 commonly asked interview questions. Working through them forced a level of self-introspection he hadn't done before, identifying his own weaknesses, where he'd made mistakes, and where he'd shown strong qualities such as teamwork, across both his personal and professional life. He described this as one of the most valuable parts of the entire process, a genuine exercise in getting to know himself better.
What are the biggest myths about ISB admission that reapplicants should ignore?
Two clear ones.
The first: that you need to come from a tier-one institute or a tier-one company to get into a school like ISB. Mayur was direct that this is not true, pedigree can help, but it is not a make-or-break factor in interview selection. What schools actually weigh is the quality of your work experience, your academic background, and your achievements. He pointed out that his own cohort includes people from a wide range of institutional backgrounds, not exclusively IITs or other elite institutes, and that the imposter syndrome many applicants feel is partly a byproduct of being surrounded by other applicants who look impressive on paper.
The second: that it's worth spending significant time trying to figure out exactly how ISB weighs its admissions criteria. Mayur's conclusion, after being admitted and observing his own batch, is that nobody outside the committee really knows the internal process, his own batch includes people whose GMAT scores are well below the class average, so the more productive use of time is securing an average or above-average GMAT score and then preparing the rest of the application wholeheartedly, rather than trying to reverse-engineer a black box.
He also directly addressed applicants who put themselves down for coming from a "tier 2 or tier 3" college: based on the range of backgrounds he's seen succeed, that self-rejection doesn't hold up, and the better approach is to focus on your own case and story rather than pre-judging yourself against an assumed bar.
What are the do's and don'ts for ISB admission, ISB essays, and the ISB interview?
On his GMAT and profile:
Don't get relaxed just because you have a high GMAT score or a strong academic background. You don't know what specific point in your application, strong or weak, the panel will focus on, so prepare every part of it wholeheartedly.
Do try to get a GMAT or GRE score that is at least the average for your target school. It's not everything, but it gives you a safer baseline to work from.
On the interview:
Try to have a genuine conversation with the panel. He noted that panelists can spot your real personality within the first five minutes of conversation if you let it show, so there's no benefit to performing a version of yourself.
Be natural, be calm during the interview.
On getting support:
Hire a good consultant, though he was careful to note this wasn't said just because of who he was speaking to. His reasoning: everyone works differently, so find a consultant you have a genuine wavelength with, someone who understands your profile well and who will give you a real, honest reality check on how the admissions process is likely to go for you specifically.
What does an ISB admission actually unlock after a long reapplicant journey?
Mayur described multiple emotions surfacing at different stages. Early on, the process felt hectic, since the application itself was built in six to seven days. That gave way to anxiety about whether he'd even get an interview call, partly because he'd chosen a virtual interview slot that placed him much later in the interview cycle than other applicants. The anxiety returned around the result date itself. After the admit came through, the dominant feelings shifted to happiness, calm, and relief.
As for what the admit unlocks, he named three things specifically:
A peer network unlike anything he'd otherwise have access to. He's now part of a cohort WhatsApp group filled with people from extremely diverse backgrounds who have done well in their own professional careers, the kind of access he wouldn't get on an ordinary working day.
Direct access to faculty. He'd previously watched several ISB professors on YouTube podcasts and admired their knowledge; now he'll get to learn from them physically, in classroom discussions.
A career transition pathway. Moving from a non-business background into business roles is difficult, and he sees an ISB MBA as the route that opens up real opportunities for that transition, though he was clear the effort to actually pursue those opportunities still has to come from the candidate.
How active is the ISB community immediately after admission?
Enough that the original group structure hit a limit, prompting the formation of an entirely new consolidated community to bring everything together. The groups themselves cover, in his words, "every small thing": badminton, cricket, groups for people from Mumbai, groups for musicians, groups organized by interest, school background, and future career interest. Case competition prep groups were already active and forming teams by the time of this conversation.
What does an ISB MBA really mean, in a reapplicant's own words?
Mayur's answer, offered half-jokingly but meant seriously: essentially, a continuous exercise in selling yourself. His reasoning: even before the MBA, during the application process, you're selling your profile and your achievements to the admissions committee. During placements, you're selling yourself to interviewers as the right fit for a role. And even afterward, in a corporate job, the same dynamic repeats indefinitely, you are always presenting and selling your value to whoever is evaluating you next.
Why does working with a consultant matter for ISB essays and ISB interview preparation?
Mayur pointed to a few concrete things, not vague praise.
Because the application itself was built in just six to seven days (something he was explicit about not recommending to anyone else), having someone available at all times mattered enormously. He specifically mentioned being able to ask even the smallest, most seemingly trivial doubts during and after the application process, and he was clear that it's not the difficult doubts that cause problems, it's the small unresolved ones that quietly turn into mistakes later, often surfacing at the interview stage.
He also pointed to the mock interview process specifically: starting from genuinely harsh feedback on his first mock, and improving steadily from there, with the feedback quality staying consistently useful throughout.
Beyond resources and mocks, the thing he emphasized most was that his consultant did not sugarcoat anything. He was told the genuine picture of where his application stood, without false hope, and he named this as the most important part of the entire engagement, more important, in his own words, than either the number of essay edits given or the specific language used in them, because you also need that same honest support after the application is submitted, heading into the interview stage.
What should an ISB reapplicant do right after an ISB admission rejection?
Nothing Mayur said suggests the answer is to simply try harder with the same approach. His entire account points the other way: write down, specifically, what went wrong the first time. Rebuild the balance between genuine representation and showcasing your strengths. Treat the interview as a real conversation, not a performance. Get a GMAT score that removes doubt as a variable. And find someone who will tell you the truth about where you stand, even when it isn't what you want to hear, because that honesty is what actually gets fixed in time for round two.
