Request a Private MBB Assessment
This is the first step in determining whether working together makes sense.
The MBB Offer Machine™ works with a limited number of candidates at any given time.
Because of this, every potential collaboration starts with an assessment of fit.
Capacity is intentionally limited to ensure depth of guidance.
We work with candidates who are decisive, coachable, and prepared to execute.
The assessment determines whether those conditions are met.
If the assessment indicates a strong fit, you will be invited to a private session with a Senior MBB Insider.
This session is used to evaluate your current position, identify gaps, and outline a realistic path to MBB readiness.
What You Can Expect
A clear, honest assessment of where you stand today, and whether an MBB offer is a realistic objective for you.
No generic advice. No obligation.

OUR CLIENTS
Who do we work with?
This system is selective by design.
We work with candidates who are already competitive, but refuse to leave outcomes to chance.
This is for you if you are in one of these situations:
You have strong academic ability and clear ambition, but interview outcomes feel unpredictable.
You want to understand exactly how screening and interview decisions are made, and how to align your performance to them.
Pedigree alone is not your strategy. Execution is.
A competitive student
or recent graduate
An early-career professional targeting MBB
You bring significant experience, and you understand that senior interviews are judged differently.
You need a system that respects your background while translating it into what MBB interviewers actually evaluate.
This is about precision,
not practice volume.
An experienced hire
with no margin for error
Who do we NOT work with?
This is not for everyone.
We work only with candidates who are decisive, coachable, and execution focused.
The MBB Offer Machine™ is not a fit for you when the below conditions are present.
X You are still unsure whether strategy consulting is the right path
X You are primarily seeking visa or work permit sponsorship
X You want motivation instead of correction
X You struggle to follow direct, expert feedback
X You expect a “done for you” solution
X You are more than 12 months away from interviewing

Built by Former MBB Interviewers
and Decision Makers
Dr. Sidi S. Koné
Former Senior Engagement Manager and Interviewer at McKinsey Former Senior Consultant and Interviewer at BCG
Dr. Sidi Koné has personally assessed and rejected candidates at McKinsey and BCG over multiple years.
That experience is the foundation of the MBB Offer Machine™.
Sidi's work focuses on one thing.
Understanding how interview decisions are actually made under pressure, and translating that logic into a system candidates can apply reliably.
Inside the program, Sidi is responsible for decision standards, evaluation logic, and enforcing what “MBB ready” truly means. No guesswork. No false confidence.
Dr. Jörn Kobus
Former Senior Engagement Manager
and Interviewer at McKinsey & Company
Dr. Jörn Kobus led large scale consulting teams at McKinsey and served on the Firm’s recruiting teams in Europe, where he interviewed and assessed candidates for years.
He brings deep expertise in structuring, communication, and senior level problem solving, particularly for complex case and fit interviews.
Within the MBB Offer Machine™, Jörn ensures candidates develop the clarity, structure, and judgment expected at the highest levels of MBB, across both interviews and real client work.
Founders' Note
from our Founders
The MBB Offer Machine™ exists for one reason.
Too many strong candidates fail not because they lack ability, but because they misunderstand how MBB decisions are made.
We saw this repeatedly from the inside.
As interviewers, as decision makers, and as mentors.
This system is not built to motivate you. Because we know that motivation is not what you are lacking.
This system is built to remove ambiguity, impose standards, and replace guesswork with judgment.
We work with a small number of candidates at a time.
Not because we enjoy rejecting interested candidates, but because enforcing standards requires focus.
If you work with us, you should expect direct feedback, clear correction, and accountability.
That is how MBB offers are earned.
Nothing more. Nothing less.
