Do you need training

Like most candidates, you share the same observation: the recruitment process in strategy consulting is a real obstacle course, selective, testing and as difficult as a Grandes Écoles competitive examination. In each round, the majority of candidates are eliminated (Table 1).

Fact #1: For every 1,000 MBB applicants, 3 will receive an offer.

Successful candidates are forced to prepare intensively. Without guidance, they need hundreds of hours of work to hope to get through the rounds to the end of the process - assuming they have had access to competent case partners and recent, high-quality resources! Traditional resources such as the Case In Point are outdated. Year after year, the average level of candidates increases; if you want to be at the top of the basket, you too will need to acquire all the codes and best practices of this very specific and standardized test.

Fact #2: Traditional preparation methods are obsolete.

In 2017, when we created PrepaStrat, there was no comprehensive, methodical preparation available to guide candidates through the entire process, from the start of their preparation right through to the final rounds of interviews. Having gone through the recruitment process ourselves and obtained offers from the best firms, we condensed all the information and experience we had gathered into a comprehensive method for learning how to succeed in board interviews, in a structured and progressive way. Since then, we've been updating our training courses several times a year, which has earned us undeniable success (Table 2).

Choosing PrepaStrat means staying ahead of the pack.

After excelling at her processes and securing an offer of an experienced CDI at McKinsey, Marie-Morgane, a former PrepaStrat bootcamp candidate, decided to accompany PrepaStrat for a few months before its official launch. A graduate of the Ecole Normale Supérieure with a doctorate in Artificial Intelligence and Deep Learning, and winner of the L'Oréal-UNESCO Young Talent Award for Women in Science, Marie-Morgane uses her pedagogical skills and exceptional learning abilities to produce new, highly advanced content.

An experienced Senior Consultant with two MBB offers under his belt, Grégory was keen to give back to PrepaStrat what the team had given him during its processes. He thus created PrepaStrat's Bootcamp offering, writing all the course materials and a book of case annals containing over 100 self-corrected case statements. An expert in case studies and strategy consulting interviews in general, Grégory has been instrumental in advising experienced candidates wishing to switch to a top strategy consulting firm after a few years' experience, in consulting or elsewhere.



A brilliant candidate with an impressive career path, Clémentine is now a consultant at McKinsey, having hit the "Grand Slam" in her processes (offers received at every firm she has worked for). Clémentine contributed to the creation of PrepaStrat's content by being the first beta-tester of the course as it was being prepared. Having fallen in love with the pedagogy that has worked so well for her, Clémentine developed the monthly Webinars offered by PrepaStrat, which enable candidates to attend the resolution of a case study live every first Wednesday of the month from 7pm to 9pm. Her kindness and sharp mind make her a valuable asset to the team.

With over 300 interviews to his credit, Alexandre is one of our most experienced coaches.
