MBB Career is an AI-powered interview training platform for candidates preparing for consulting, investment banking, private equity, venture capital, strategic investment, and resume-based interviews - built so that practice feels as close to the real interview as possible.
This is not a place to watch lectures or read study materials. It is a sparring ground for people who have already covered the fundamentals - casebooks, technical guides, resume prep - and now need to perform under real interview pressure: building structure, running the numbers, defending answers, and turning feedback into improvement.
Candidates with strong networks of seniors, alumni, and industry contacts can run multiple mock interviews with practitioners before the real thing. Many candidates never get that chance - and even study groups often grade each other by standards very different from how actual interviewers evaluate. MBB Career was built to close that gap.
You run a roughly 60-minute live interview with an AI interviewer, and when it ends you receive a scorecard built on the same criteria used in real hiring processes. The goal is not to hand you answers - it is to show you exactly where you are strong and weak across structuring, quantitative analysis, judgment, communication, and synthesis, and to let you retry until your odds in the real interview go up.
MBB Career was built by a practitioner who has worked across consulting, investment banking, strategic investment, private equity, venture investing, and M&A - firsthand, on the deals and in the interview rooms.
The founder completed an engineering undergraduate degree in the US and an M7 MBA, with roughly ten years of career in the US and eight in Korea. Moving through investment banking and MBB consulting to a current role as a Principal Investor, he has sat on both sides of the hiring table - as the candidate being evaluated and as the interviewer doing the evaluating.
He passed interviews at all three MBB firms, went through more than 40 interviews at bulge-bracket investment banks and major financial institutions, and more than 20 interviews for Principal Investor positions. He has since conducted over 50 interviews himself, evaluating candidates for consulting, investment banking, private equity, growth equity, and strategic investment roles.
As a Principal Investor he has worked on both the strategic and financial sides - strategic investments, growth equity, full buyouts, M&A, partnerships, valuation, due diligence, investment committee, negotiation, and PMI. This service was not designed from prep books; it was designed from a working sense of what actually matters in real deals and real hiring.
MBB consulting, investment banking, PE, VC, strategic investment, and corporate development interviews are not knowledge quizzes. They test whether a candidate can structure a problem under time pressure, interpret ambiguous information, handle numbers, make a call, and defend that call persuasively.
The problem is that most candidates cannot practice in an environment that resembles the real interview. You can read every casebook and still not know when a real interviewer intervenes, which answers read as weak, what level clears the pass bar, and where an answer slips into borderline.
MBB Career was built to solve exactly this. It tests whether what you studied alone actually comes out under interview conditions, runs you through challenges, hints, time pressure, and follow-up questions at a real interviewer's cadence - and afterward gives you a concrete scorecard and improvement points, not vague advice.
MBB Career currently centers on three products: the Consulting Case Interview, the IBD / PE / VC Interview, and the Resume Review Interview.
In the Consulting Case Interview, an AI interviewer in MBB partner style presents a case just like the real thing - following up, pushing back, dropping hints, and assigning exhibit reads and calculations based on your answers. When the case ends, you receive a scorecard across structuring, quantitative analysis, business judgment, synthesis, and communication.
The IBD / PE / VC Interview covers technical and investment-judgment interviews for the major finance tracks - M&A, ECM, DCM, S&T, PE, and VC. It is not built on memorization questions; it mirrors how practitioners actually probe a candidate's thinking, deal understanding, valuation, market view, investment thesis, and risk assessment.
The Resume Review Interview stress-tests your resume against your target role the way a real interviewer would - career narrative, deal experience, leadership stories, motivation, fit, and weaknesses. The point is not copy-editing; it is finding out whether what's written on your resume survives the room, and which questions make your answers collapse.
On price, this is also the economical option. A one-on-one mock interview with a current or former consultant or banker typically runs $150-$250 per hour - meaning a single session with feedback costs about as much as, or more than, six months of MBB Career. Here, one payment buys six months of repeated 60-minute live interviews with scorecards - dozens of full-pressure reps for the price of one or two hours of human coaching. And unlike casebooks or content subscriptions, every session is a real interview under pressure with personalized feedback, so the density of practice per dollar is on a different level.
Half of a case interview is decided in the first seven minutes. How you ask clarifying questions, and whether you volunteer a top-down structure without being asked - partners read that in real time. This isn't a theory we invented; it's something we saw candidates get wrong, over and over, while coaching them directly.
Case Start Drill isolates exactly that first seven minutes and drills it on repeat. You hear the opening, attempt clarification and a top-down structure, and get a single Structuring verdict on the spot - Fail, Borderline, or Pass - with tags showing exactly where you lost points. It doesn't run the case to the end like a full 60-minute session, so a rep takes minutes, and there are currently 120 openings to draw from.
This wasn't a curriculum we made up. Coaching real candidates showed us that this first seven minutes is where structurally weak candidates fail the most, and fail the same way, every time - and that isolating just that moment for repeated reps is the most effective way to fix it. The scoring standard and methodology are the same as the full 60-minute case.
The interview flow and scoring criteria are grounded in the founder's own interviews at MBB, bulge-bracket banks, and Principal Investor roles - and in his experience evaluating candidates as an interviewer.
This is not a service made by feeding public casebooks into an AI. The cadence and scoring rubric were designed around how real interviewers actually run a case: the pace, when they challenge, which answers register as strong versus weak signals, and what separates a pass from a borderline.
The standards were then beta-tested with industry colleagues and practitioners - and calibrated strictly enough that even people with real consulting, banking, investing, and corporate strategy experience did not pass easily. The goal is not to make you feel good. It is to surface your weaknesses as early as possible, before the real interview does.
MBB Career is built for candidates preparing for consulting, investment banking, PE, VC, strategic investment, corporate development, MBA recruiting, and experienced-hire transitions.
It is especially useful if you have covered the fundamentals through casebooks or courses but lack a real sparring partner; if your senior or alumni network is limited; if repeated mock interviews are hard to arrange; or if you want to know whether your answers clear the actual hiring bar - pass or borderline.
It also serves experienced candidates. Experienced-hire interviews turn less on knowledge and more on how clearly you structure your actual experience, how precisely you articulate your role on a deal or project, and whether you hold up under a senior interviewer's follow-ups.
The point of MBB Career is not to memorize answers - it is to build the thinking patterns and answering habits that work in a real interview.
Through live-format interviews you test your structuring, numeracy, business judgment, and communication style. Afterward, the scorecard shows you exactly where you are strong and where you are weak - and you close the gaps by repeating the same case or taking on new ones.
In the end this service delivers one thing: as much real interview pressure as possible before you walk into the room, an objective read on what you are missing, and repeated training that raises your odds when it counts.
