Selection in consulting firms starts before the first round... with the shortlisting tests 

"How to prepare professionally yourself for the shortlisting tests of the McKinsey 's Problem Solving Test "

How to get more than 80% of the answers correct at McKinsey's PST...


Are you fed up with fighting alone, in a corner training yourself for the shortlisting tests of consulting firms? You don't know where to begin in order to become competitive when facing the diversity of shortlisting tests, including: McKinsey's PST, Potential Test from the Boston Consulting Group, Serious game from Accenture etc. Then carefully read the following; I have the precise solution you need in order to become competitive on all these tests in a minimum amount of time.

I am Victor Mamou, former consultant at the Boston Consulting Group and also accepted at McKinsey. I'm specialized in preparing job interviews in consulting firms by following an approach called the Integral Method that sends several hundred candidates to the best consulting companies each year. Indeed, I train several hundred candidates each year and my seminars are integrated in the most prestigious institutions like Ecole Polytechnique, HEC Paris, ESSEC, ESCP, EM Lyon or even EDHEC and Arts et Métiers. These institutions are partners of the Ivy League universities in the U.S. I will tell you the mistake I've made with dozens of candidates  in previous years concerning shortlisting tests

Mea culpa, since I make seminars to prepare people for interviews in consulting, my principle is to focus on case studies around which the Integral Method is built.

The shortlisting tests? I considered that no specific preparation was needed for them. In theory, the skills needed to succeed at these tests rest on the same base as the one needed to succeed at case studies; however,  this is far from the truth in practice.

I have to admit I was totally mistaken on this one...

I was coaching candidates without particularly focusing on these shortlisting tests. The feedback from the candidates showed me that training oneself only for case studies isn't enough to prepare for McKinsey's PST and other shortlisting tests. McKinsey's PST indeed imposes many constraints likely to destabilize every candidate that isn't specifically prepared for this test.

To say it another way, you can absolutely be competitive for the interviews at McKinsey and fail the shortlisting tests of this firm! This is the feedback from several candidates who easily had the level for the case studies, but who failed at the Problem Solving Test. This made me become aware of the specific difficulty of preparing for these shortlisting tests.

 Here are the specific difficulties of the tests that look like McKinsey's PST:

  • The necessity to manage your time in a specific way, in a context where you have to reason and calculate  a great deal in a very limited amount of time.
  • The impossibility to share your questioning with anybody: the coldness of the computer screen or your sheet of paper will be your only support. 
  • Shortlisting tests are much more complicated than classical logic tests, such as the  GMAT.
  • high failure rate, especially when candidates are not well prepared to this kind of test. 
  • Interesting free preparation supports available online are still insufficient to have the required skill level on D-Day.

How to measure yourself for these specific challenges?

 To succeed at McKinsey's Problem Solving Test, you will have to:

  • Reinforce your time management for this specific type of test; you’ll need to quickly identify your weak points.
  • Become accustomed with the most classical reasoning sequences in these tests.
  • Train yourself on a series of questions especially developed to enable you to test yourself beforehand... so that your potential failures are limited to your training sessions.
  • Aim for score of 80% or higher in the time given.

To enable you to succeed at these shortlisting tests, I've decided to set up a specific preparation process to help you prepare for PST tests and achieve a score of 80% or higher.

Setting up this new preparation tool hasn't been easy. It’s required numerous test sessions and taking into account the remarks of the candidates before and after their interviews, in order to develop my exclusive preparation tool for McKinsey's Problem Solving Test.

Here is THE method to succeed at the McKinsey PST

This is a digital book that will enable you to succeed without mishap at this redoubtable selection test :

  • Unreleased tests – To stand out from the other candidates and complete your preparation in addition to the free tests that “everybody trains on.”  
  • Intensive training on all the difficulties of McKinsey's PST – Logic tests, calculations, business sense, strategic decision-taking, graph and data analysis.        
  • A detailed solution for each question – In order to enable you to “think like a consultant,” because PST isn't only an academic test!

You will progress very quickly on this shortlisting component

The succession of questions is elaborated so that at the end of the book, you will be competitive for this test. Every question has a comprehensive solution so as to make the job easier for you.

"The score of students has gone from less than 40% of success to more than 70% after the training seminar on two of the tests [out of the 3 contained in the book, which explains they haven't reached 80% of correct answers.]"

- Management of a leading business school

Train yourself thanks to the content of the book and...

  • Be competitive on all shortlisting tests – The PST is a more complete and complex test than other shortlisting tests: kill two birds with one stone !
  • Prepare your quantitative cases mastery – The 3 complete PST tests corrected in this book contain key reasoning sequences that you will find in many cases.
  • Test your analytic skills – Especially concerning the first round cases: data, table, graph analysis etc.

Our references


Give yourself the chance to succeed at the shortlisting tests in consulting groups, with a very short preparation time.

How much will this cost me?

The content of the training to ace McKinsey's PST is partially given in preparation seminars in several reference institutions, on a selective basis – all students of the concerned Grandes Ecoles don't have access to this training. Typically, we deal with two PST tests in detail during a day of work and I charge a minimum amount of $1,200 excluding tax for a day of training.

Value of two tests

Value of the additional test





In short, concerning the content of the training, I charge my institutional clients around $1,800 excluding tax for this exclusive tool, which is crucial to getting invited to the first rounds in most consulting firms. 

My goal with, is to contribute to open the consulting sector to most people, so no I won't set the price of this content to $1,800 excluding tax, not even $600, $400 but rather $67

  • Secure payment

And what if the book doesn't suit me afterwards?

Let's be clear, I don't do this to generate disappointment within my clients. All my trainings and books are reimbursed if you're not satisfied within 30 days. Concerning the preparation to strategy consulting, I know the quality of my training, that's why there is that guarantee :)

I wish you the same success with this book than the previous readers!

To your success,

Victor Mamou
