A Bengaluru-based IT services engineer with a 720 GMAT and four years at Infosys gets an HBS interview invite. She spends three weeks rehearsing 45-minute behavioural scenarios. The actual HBS interview is 30 minutes, fires roughly 30 rapid questions, and ends before she finishes her second prepared story. This is a common pattern: Indian applicants prepare for a generic "MBA interview" that does not exist. Every programme runs a different format, and the format determines what wins. This post breaks down the interview structure at each major school so you can prepare for the right test.
The format table: what each school actually runs
Here is the reference table for the 2025-26 and 2026-27 cycles, drawn from official school pages and Poets&Quants' school-by-school interview data.
HBS: 30 minutes. Conducted by an admissions board member who has read your full application. Rapid-fire, roughly 30 questions. Two interviewers are common (one asks, one observes). Post-interview written reflection due within 24 hours. Virtual or in-person.
Wharton: 35-minute Team-Based Discussion (TBD) with 5-6 candidates, followed by a 10-minute individual interview. The TBD includes 60-second opening statements, a 25-minute group discussion, and a 5-minute group presentation. Currently all virtual. The 2025-26 prompt asked candidates to design a Leadership Intensive within a $25,000 budget.
Stanford GSB: 45-60 minutes. Blind interview: the interviewer has only your resume, not your essays or scores. Competency-based behavioural questions for 30-40 minutes, then 15 minutes for your questions. Conducted by alumni or admissions staff, remote or in-person.
Chicago Booth: 45-60 minutes. Blind: interviewer sees only your resume. Conversational, not heavily behavioural. Requires a separate 60-second video essay before the interview (not shared with the interviewer). Conducted by students, alumni, or admissions staff.
Kellogg: 30-45 minutes. Blind: interviewer has only your resume. Conducted primarily by alumni. You schedule your own interview within six weeks of the deadline. Behavioural focus on teamwork, leadership, and collaboration.
MIT Sloan: 30 minutes. Full-application review: the interviewer has read everything, including recommendations. Behavioural Event Interviewing (BEI) format with 3-6 deep behavioural questions and follow-up probes. Requires a pre-interview short-answer submission and data visualisation 24 hours before.
INSEAD: Two separate alumni interviews, each 25-40 minutes. One interviewer shares your professional background; the other has a contrasting profile. One interview tests cultural fit; the other tests intellectual depth and career clarity. Conducted in your city or country.
LBS: Two-part process. First, a KIRA video interview: two questions, 45 seconds prep and 90 seconds to respond per question. Then a one-on-one interview with an alumnus, typically 1-2 hours, including a case presentation component (10-15 minutes). The interviewer has read your full application.
Columbia: 45 minutes. Blind: interviewer has only your resume. Conversational and resume-based. Conducted by admissions committee members or current students, all virtual.
If you are an IT services or consulting professional targeting US M7
The biggest format trap for Indian IT and consulting applicants is the blind interview at Stanford, Booth, Kellogg, and Columbia. In a blind interview, the interviewer has only your resume. That means the interviewer does not know your GMAT score, your essay narrative, or your recommender's comments. Every claim you make in the room must stand on its own.
Indian applicants from Infosys, TCS, Wipro, and the Big Four tend to rehearse answers that reference their essay themes. In a blind interview, those references land flat because the interviewer has no context. The fix: build five standalone stories (leadership, failure, teamwork, ethical dilemma, impact) that work without any setup from your written application. Each story should run 60-90 seconds. Anything past 120 seconds loses the interviewer, according to interview prep research from Menlo Coaching.
For HBS and MIT Sloan, the dynamic reverses. The interviewer has read everything. Indian applicants who repeat their essay content verbatim waste the 30-minute window. Instead, go deeper on one experience the essay mentioned briefly, or offer a perspective you did not have space to include in the written application.
If you are a final-year student or early-career applicant (0-2 years)
The Wharton TBD is the format that surprises early-career Indian applicants most. The 35-minute group discussion requires you to collaborate with five strangers in real time, agree on a proposal, and present it. Indian applicants with limited professional experience often default to one of two failure modes: dominating the conversation to "prove leadership," or staying silent to "show they are a team player." Both are penalised.
The Wharton admissions page states the TBD evaluates teamwork, communication, and leadership. The signal they look for is neither volume nor silence. It is the ability to build on someone else's idea, redirect a stalled discussion with a question, and volunteer to present the group's work even if the final proposal was not your idea. For a deeper breakdown, see our Wharton TBD guide for Indian applicants.
For INSEAD, the two-interview structure is unusual. The first alumni interviewer often shares your industry background, so the conversation can go deep into sector-specific questions. The second interviewer deliberately comes from a different world. Indian applicants who prepare only for "why MBA" and "tell me about yourself" get caught when the second interviewer asks about geopolitics, a recent policy change, or a country they have never visited. Read widely in the month before your INSEAD interviews.
The three variables Indian applicants misjudge
Variable 1: Duration does not equal difficulty. HBS runs 30 minutes but fires 30 questions. LBS runs up to 2 hours and includes a mini case. Indian applicants assume the longer interview is harder. In practice, the 30-minute HBS interview leaves the least room for recovery. One fumbled answer at HBS costs you 3% of your interview time. One fumbled answer at LBS costs less than 1%.
Variable 2: Blind vs. informed changes your entire preparation strategy. At Stanford, Booth, Kellogg, and Columbia, the interviewer has only your resume. At HBS, MIT Sloan, and LBS, the interviewer has your full file. Preparing the same way for both is the single most common format mistake Indian applicants make. For blind interviews, your stories must be self-contained. For informed interviews, your stories must add new information that the file does not already contain.
Variable 3: Pre-interview submissions are scored, not decorative. MIT Sloan requires a short-answer response and a data visualisation 24 hours before the interview. HBS requires a post-interview written reflection within 24 hours. LBS requires a KIRA video with 45-second prep windows. Indian applicants who treat these as formalities lose points before the conversation starts. These submissions are part of the evaluation, and at MIT Sloan, the interviewer reads your pre-interview submission before asking the first question.
The format-specific preparation calendar
If you are applying to three or four schools with different formats, your interview preparation cannot be a single rehearsal track. Here is a realistic allocation for an Indian applicant with a full-time job:
For blind-interview schools (Stanford, Booth, Kellogg, Columbia): spend 60% of your prep time building five standalone STAR stories that work without application context. Record yourself. Cut every answer to under 90 seconds.
For informed-interview schools (HBS, MIT Sloan, LBS): spend 60% of your prep time identifying gaps in your written application. What did your essays not say? What context did your recommenders miss? That is your interview material.
For the Wharton TBD: run at least three mock group discussions with strangers, not friends. Friends accommodate you. Strangers reveal your default group behaviour. Our 7-day MBA interview prep plan covers this in detail.
For INSEAD: prepare for two conversations with two different people who want two different things. The first wants depth in your domain. The second wants breadth in your worldview. Read one non-business book and one policy briefing before interview day.
What this means for Indian applicants
The MBA interview is not one thing. It is nine different tests at nine different schools, and the Indian applicant who prepares for "the MBA interview" as a category is preparing for something that does not exist. The format determines the skill being tested: rapid recall at HBS, collaborative instinct at Wharton, standalone storytelling at Stanford, intellectual depth at INSEAD, case reasoning at LBS.
Pegasus Global Consultants has coached Indian applicants through all nine of these formats over 13 years. The pattern we see most often: candidates spend 80% of their prep time on content (what to say) and 20% on format (how the interview actually works). The ratio should be reversed. If you know the format, the content follows. If you know only the content, the format catches you. A profile evaluation before interview season helps identify which format gaps to close first.

Common questions applicants are asking
Do all M7 schools interview every applicant? No. HBS, Stanford, and Wharton interview by invitation only, typically 20-25% of applicants. Kellogg aims to interview as many applicants as possible. MIT Sloan is invitation-only. Booth is invitation-only. Columbia is invitation-only. If you receive an interview invite from HBS or Stanford, the admit rate from the interviewed pool jumps significantly compared to the overall admit rate.
Can I choose between virtual and in-person interviews? It depends on the school. Wharton TBD is currently all virtual. HBS offers both. Stanford offers both but does not allow on-campus requests. Kellogg offers both. LBS prefers in-person for the one-on-one component. INSEAD interviews happen in your city, so the format depends on alumni availability. Columbia is all virtual. Check each school's current policy before assuming you can fly to campus.
How do I prepare for a blind interview if I have a non-linear career? This is the most common concern from Indian applicants with career switches (engineering to product, consulting to startups, finance to social impact). In a blind interview, the interviewer sees only your resume. If your resume does not tell a clear story on its own, the first two minutes of the interview become an explanation exercise instead of a demonstration exercise. Rewrite your resume specifically for blind-interview schools so the career logic is visible without supplementary essays.
Is the Wharton TBD harder for introverts? The TBD is not a debate. It is a collaboration exercise. Introverted Indian applicants who listen well, synthesise others' points, and volunteer to present the group's conclusion often score higher than extroverts who dominate the floor. The skill being tested is contribution quality, not speaking time.
Does INSEAD penalise Indian applicants who have never lived abroad? Not directly. But the second interviewer will test your global awareness. If your entire professional and personal life has been in one Indian city, prepare to discuss international business trends, geopolitical shifts, or cultural differences with specificity. A well-read applicant from Pune who can discuss EU trade policy intelligently will score higher than a returned-NRI who cannot explain why they want to go back abroad.
