Internships and programs at Oliver Wyman

The early-career programs it runs for students and recent graduates, by the names it uses for them.

Summer Intern (core consulting): The core management consulting internship. Interns work in teams on client problems, doing research, data work, and quantitative, strategic, and financial analysis, with a training week and mentorship. The summer 2027 US posting offered five tracks: Generalist Consulting; Banking & Financial Services; AI, Data, Analytics & Advanced Applications; Technology-Driven Transformation & Change Implementation; and Private Equity, Deals, Diligence & Post Transaction.
Summer Analyst, Data and Analytics (DNA): An 8-week, client-facing analytics internship in DNA, Oliver Wyman's quantitative team. Interns build models and analyses on large datasets using tools such as Python, R, and SQL. The 2027 US posting was based in Raleigh and limited to one graduating class.
Actuarial internships: Summer internships in Oliver Wyman Actuarial, including life practice roles in several US offices, plus Government Health Consulting college program internships in actuarial, financial, and informatics tracks.
MBA Summer Associate: The MBA internship, posted by practice area, such as health and life sciences, and recruited on a separate timeline from undergraduate roles.

When Oliver Wyman posts internships

The core US internship now recruits a full year early, like McKinsey's. The summer 2027 US posting covered Boston, Chicago, Dallas, Houston, New York, San Francisco, and Washington, DC, was open to second-year students in the class of 2028, and closed March 29, 2026. Expect the summer 2028 version to follow a similar winter-to-spring window, but confirm on the posting.

Specialty roles post separately on the Marsh careers site with their own deadlines. The US Data and Analytics summer analyst role for summer 2027 went up in late summer 2026 with a fall deadline, and actuarial and health consulting internships for the same summer were posted that fall. Other regions, London included, run their own calendars.

Who can apply

The summer 2027 core US internship required second-year undergraduates (class of 2028) in a four-year program, from any major. Specialty roles are narrower: the 2027 US DNA posting was open only to the class of 2028 and asked for a quantitative background such as math, statistics, economics, computer science, or engineering.

Both the core US internship and the DNA posting required unrestricted US work authorization, and Oliver Wyman stated it does not sponsor visas for them; the core posting also noted that CPT and OPT count as restricted authorization. Check each listing's work authorization line.

The interview process

Oliver Wyman describes a mix of conversational and case interviews. Conversational interviews cover your background, interests, and goals. Case interviews are interactive exercises built on real client problems that test how you approach unstructured challenges.

The firm publishes six sample cases on its interview preparation page and advises treating the interviewer like a client who wants you to succeed. Data and analytics and actuarial candidates should also expect questions on the technical skills listed in the posting.

Tips for applying to Oliver Wyman

Work through Oliver Wyman's own published practice cases before your interviews. They show the style the firm uses.
Sophomores: the core US internship window closes in late March, so treat it like McKinsey's and apply in the winter.
Match the track to your skills. A quantitative student may fit DNA, actuarial, or the AI and data track better than generalist consulting.
Check the graduation class and work authorization lines on each posting, since roles can be limited to a single class year.
