What You Will Do

As a new joiner at Oliver Wyman, you will have the opportunity to work on interesting problems for large clients worldwide, developing your expertise quickly and making an immediate impact. You'll work alongside senior colleagues and clients, working as one to help to solve complex problems and drive meaningful change.

Why Join Us

Come aboard if you enjoy solving interesting problems and at ease working across different cultures. You will step out of your comfort zone, finding stretch opportunities along every step of the journey. You will also find genuine colleagues who speak their minds and measure success not by the number of hours worked but by what gets accomplished.

Immediate impact, continuous challenge

• Internships at Oliver Wyman provide a true taste of life as a consultant and unique preparation for a full-time role.

• During your internship from June to August, you’ll work on 1-2 challenging projects that have a significant impact on clients, industries, and societies.

• You’ll be a full team member, with responsibility for a distinct piece of work that will help the team deliver breakthrough impact.

• You will be based in Tokyo office but may have the opportunity to travel for project work.

• We’ll ask you to challenge the norm and strive to build something new to shape our firm and the world around us.

Chart your course; we support the journey

• Throughout your internship, we will demonstrate our commitment to your growth and development, and to helping you chart your post-graduate course.

• You’ll learn on the job via our apprenticeship model. Much of your focus will be on research and analysis, and you may also have opportunities to begin developing your communication, presentation, and client-management skills.

• We care about you succeeding and you’ll be supported every step of the way. You will be mentored and coached by numerous colleagues, from partners and consultants to a dedicated “buddy,” formal “mentor,” and an “intern captain” overseeing the program.

We hire you to be you

• Our open, inclusive, and down-to-earth culture will enable you to bring your authentic self to work.

• There’s no corporate mold to fit and hierarchy doesn’t get in the way.

Who Can Apply

• We look for people who display initiative, intuition, and creativity with a strong problem solving and analytical mindset.

We value extracurricular activities and evidence of leading an interesting and impactful life outside of your studies.
