How Did a Consulting Professional Convert NUS MBA?

Aditi Aggarwal, a consulting professional with experience at KPMG and Accenture, shares her journey of converting NUS MBA — building a comprehensive story repository from 30-40 introspection questions, navigating fundamentally different interview formats at NUS and ISB, and discovering that documenting every life experience is the single most important step in the entire MBA application process.
Consulting professionals arrive at the MBA application process with a paradox: they are expert story-tellers for their clients, but they often struggle to tell their own story. They spend their careers framing other organisations' challenges, designing solutions, and presenting recommendations to senior stakeholders. This gives them polished communication skills and structured thinking. But when it comes to introspecting about their own career — articulating why they made the choices they made, what patterns define their professional identity, and where they want to go — the analytical lens they apply to client problems suddenly feels unfamiliar.
Aditi Aggarwal navigated this paradox successfully, converting NUS MBA — one of Asia's most respected business programmes — while also interviewing at ISB PGP. Her comparative account of both interview experiences, combined with her systematic approach to application preparation, offers practical value for any consulting professional managing multiple school applications.
Why Is a "Story Repository" the Most Important Asset in MBA Applications?
Aditi was candid about her starting point: "I was totally lost when I was researching colleges and looking at their applications."
The turning point was the introspection questionnaire: "The questionnaire that you shared — I don't know how many questions, around 30-40 or even more — they really probed me to think. They helped me capture the key elements in my life."
The concept of a "story repository" is what separates strategic applicants from reactive ones. Instead of approaching each school's essay questions cold — staring at a blank page and wondering what to write — the repository approach first documents everything comprehensively. Every professional achievement, personal growth moment, leadership instance, failure, learning, and motivation goes into a single structured inventory. Only then do you begin selecting stories for each school's specific questions.
"That's very important — getting your story repository correct and really documenting everything that has happened in your life. Because then somehow they play a key role in your story, in your overall brand that you showcase to the college."
The "brand" concept is important. Your MBA application is not a collection of disconnected answers to disconnected questions. It is a coherent brand presentation — a unified portrait of who you are, what you have done, where you want to go, and why this particular school is the right vehicle to get you there. The story repository provides the raw material. The consultant helps you curate and sequence that material into a compelling brand narrative.
"In a career of three or four years, you actually go through so many things. It's very important to sync it up together and have a very clear and crisp strategy that you want to present."
"The questionnaire helps you get started and put everything down at one place. That's the initial step for this."
For consulting professionals who have spent their careers building frameworks for others, applying that same framework discipline to their own narrative is both challenging and ultimately natural. The questionnaire provides the structure. The consultant provides the external perspective. The result is a story repository that serves every school application and every interview.

How Different Are NUS and ISB Interviews — and What Does Each Test?
Aditi interviewed at both NUS and ISB — and her comparative account reveals two fundamentally different evaluation philosophies. Understanding these differences before walking into the interview room is a genuine competitive advantage.
NUS MBA interview — conversational fit assessment (20 minutes):
"A 20-minute interview. Two panellists — one from the career services team and the other from the admissions committee. Pretty decent, mostly conversational."
The NUS interview is designed to assess fit and authenticity in a low-pressure environment. The questions follow a recognisable arc: "They asked me why MBA, why NUS, post-MBA goals, and then 'tell me about the worst day you had at your office.'"
The "worst day at the office" question is characteristic of the NUS approach — they want to see how you reflect on difficult experiences, what you learned, and how you communicate vulnerability without losing professional composure. "They don't grill you at all. You don't even feel like it's an interview."
The conversational format rewards candidates who are genuinely comfortable with their story — not candidates who have memorised scripted answers. The moment you shift from natural storytelling to recitation, the panel can tell. For consulting professionals accustomed to client presentations, the NUS format should be comfortable — but only if the preparation is genuine rather than performative.
ISB PGP interview — deep work experience interrogation (40 minutes):
"A 40-minute interview. Three panellists, all alumni. My ISB interview mainly revolved around work experience."
The ISB interview is twice as long, has more panellists, and focuses almost exclusively on work experience depth. This is not a fit assessment — it is a verification exercise. The panel is checking that you genuinely own the achievements described in your application.
"They were very interested in what I had done at KPMG, what I had done at Accenture, how was it different, where did I fail, where did I succeed, what were the parameters, why did I fail, and what were the learnings. I would say 95% of my ISB interview was around work experience."
For consulting professionals, this means being prepared to discuss specific client engagements in detail — not at the framework level ("we used a market-entry strategy framework") but at the operational level ("the client was a mid-size FMCG company entering Southeast Asia, and the specific challenge was distribution network design in a fragmented retail market"). The ISB panel wants to hear your individual contribution, not the team's work.
The preparation insight that bridges both interviews: "While preparing for the interview, I would suggest future candidates to really go through their applications. They should be very thorough with what they've written in their essays, in their resume — even things like hobbies and interests."
And a strategic addition: "Apart from your application, you should have two-three pointers which you haven't mentioned but you can tell them as stories or anecdotes during the interview."
This "extra stories" technique is powerful. The panel expects you to be prepared for questions about your application content. They do not expect you to have additional material ready — stories that demonstrate qualities not covered in your essays. Having these ready signals depth and genuine self-awareness.

Why Should Consulting Professionals Target Singapore MBA Programmes?
The NUS MBA offers specific advantages for Indian consulting professionals that are worth examining beyond generic "international exposure" reasoning.
Singapore's position as a hub for Asia-Pacific consulting operations means that NUS's alumni network, recruitment partnerships, and career services are specifically optimised for consulting career progression in the region. Firms like McKinsey, BCG, Bain, Accenture Strategy, and Deloitte all have significant Singapore operations — and NUS is a target school for their Asia-Pacific recruitment.

For Indian consultants at KPMG or Accenture — as Aditi was — the NUS MBA creates a career pathway from Indian consulting operations to regional or global roles. The programme's diverse cohort (typically 80-90% international students from 30+ nationalities) provides the cross-cultural working experience that international consulting roles demand.
The one-year format also minimises career interruption — particularly valuable for consulting professionals whose client relationships and project portfolios deteriorate with extended absence.

What Are the Key Dos and Don'ts for Future NUS MBA and ISB Applicants?
Aditi's recommendations are concise, prioritised, and tested against her own experience.
Do: Get GMAT out of the way as soon as possible. "Don't fret on the score." The GMAT is a threshold requirement, not a differentiator for most applicants. The time and energy saved by finishing early is better invested in application preparation.
Do: Start applications early. "So that you're able to meet Round 1 and Round 2 deadlines." The cascade of Round 1 deadlines across NUS, ISB, and other schools creates a logistical challenge that only early starts can manage.
Do: Be authentic. "Portray what you've done well so that it captures the key highlights of your overall journey — professional as well as personal." Authenticity is not the absence of strategy. It is the foundation on which strategy is built.
Do: Build a story repository before writing any essays. The 30-40 question introspection process creates the raw material that serves every application. Without it, each school's essays are approached from scratch — an enormously inefficient process.
Do: Keep 2-3 unpublished stories for interviews. Material that is not in your essays but demonstrates additional qualities creates a powerful impression of depth.
Don't: Focus too much on your GMAT score. "I'm stressing on this because I did this myself." Score obsession delays applications and creates unnecessary anxiety.
Don't: Use ChatGPT or Google Gemini for essays. "Be authentic to yourself." AI-generated content lacks the personal specificity that admissions committees evaluate.
Don't: Prepare identically for NUS and ISB interviews. NUS tests fit (20 minutes, conversational). ISB tests work-experience depth (40 minutes, probing). The preparation must match the format.

Key Takeaways for Consulting Professionals Targeting NUS MBA
Build a story repository before writing any essays. Document every significant career experience. Select from the repository for each school's specific questions.
NUS and ISB interviews are fundamentally different. NUS is conversational and fit-focused (20 minutes). ISB is work-experience-intensive (40 minutes, 95% work experience questions). Prepare for each specifically.
Keep 2-3 unpublished stories for interviews. The best interview candidates have more material than what appears in their application.
Get GMAT done early — and do not obsess over the score. The application and interview carry far more weight for most candidates.
Authenticity is non-negotiable. Do not use AI tools for essay content. The admissions committee evaluates self-awareness, not writing polish.
Consulting professionals must learn to frame their own story, not just their clients' stories. The introspection questionnaire forces this transition.
Singapore offers specific career advantages for Indian consulting professionals. NUS's Asia-Pacific consulting recruitment network is a tangible post-MBA asset.
