Guillaume Is a Collaborative Challenger

Principal, Paris

At BCG, Challengers go against expected thinking and inspire their teams to be truly innovative. Guillaume empowers and inspires others.

At BCG, I discovered that curiosity can never be quenched. The more you feed it, the bigger it gets!


In Guillaume’s Words

I cannot think of many careers that offer as many discoveries and challenges as BCG. At the end of my business studies, I had chosen the consulting business, in which I knew I could satisfy my curiosity and thirst for learning. I have not been disappointed. In less than ten years, I worked in various industries and on many issues and traveled to India, Burma, Russia, China, Gabon, and Congo. A true immersion in globalization. At a very early stage in my career at BCG, almost by accident during an assignment, I discovered the retail and consumer goods universe, which has since then become my specialty and in which the ability to continuously test new ideas with consumers stimulates creativity.

I spent two years in the Boston office of BCG. I was appointed project leader there, which was a key step in my career, and I learned to anticipate and facilitate teamwork. Now a principal, I mostly work on the assumptions and hypotheses that will need to be investigated during the assignment. I also support partners in building BCG's relationships with its clients. Today, I look at my personal and professional development since 2009 with grateful and surprised eyes!

About Guillaume

Guillaume is an HEC Paris (French business school) graduate. He discovered the consulting business and BCG during his year-off internship in 2008 and came back as an associate after he completed his studies with a digital major. Since then, he has split his time between the Paris and Boston (2012-2014) offices.


Q: What is a typical day like for you?

A: I always start the day with my family and drop off my children at school. Yet once I get to the office, no two days are alike. I may attend meeting after meeting with clients, spend time with my team to work on the project, help consultants on methodology matters and coach them, or exchange views with my partner(s). This job is highly demanding but it does not rule out relaxation and fun. It is a matter of tradeoffs. As for me, I like having lunch with the many friends I have at BCG. During the rest of the day, I remain focused and efficient in order to get back home early enough for my children's bedtime and share a pleasant dinner with my wife at the end of our working day.

Q: What international experiences have been the most interesting for you?

A: Between 2012 and 2014, BCG enabled me to temporarily transfer from the Paris office to the Boston office, a city where my wife had decided to resume her studies. What a tremendous opportunity! Onboarding was extremely easy. I discovered the same working methods, the same international exposure and issues, and the same extremely strong corporate culture. This continuity made it possible for me to take full advantage of this extremely rich experience abroad: meeting new passionate and fascinating colleagues and discovering a new business environment. And, last but not least, I acquired unforgettable memories with my whole family!

Q: If you weren’t working at BCG, what would you be doing?

A: I might be—or at least try to be—a senior official. To me, serving the state, and through it my fellow citizens, is not only a noble mission but also a vital one. I particularly value the efforts that BCG has been making for many years, in France and abroad, in order to take part in the public debate and contribute to the emergence and promotion of new ideas with pragmatism, curiosity, and humility, without any ideological bias.
