About the company

Marsh McLennan

Company overview
Marsh McLennan is a professional services group focused on risk, strategy, and people. The company operates through four global businesses: Marsh (insurance broking and risk advisory), Guy Carpenter (reinsurance), Mercer (people consulting and benefits), and Oliver Wyman (management consulting). Marsh McLennan serves large and mid-sized organisations across industries, plus public-sector clients, helping with insurance placement, risk analytics, workforce and retirement solutions, and strategy projects. In the latest annual reporting, Marsh McLennan describes more than 90,000 colleagues advising clients across more than 130 countries.

Locations and presence

Marsh McLennan operates globally with major hubs including New York and London, plus large regional offices across North America, Europe, and Asia-Pacific. Hybrid expectations vary by team, but multiple early-career postings spell out an expectation of being in the local office or on-site with clients at least three days per week, with at least one shared in-office anchor day.

Palpable Score

73.8
/ 100
Marsh McLennan is a strong early-career option because the company offers several entry routes across the group, from Marsh graduate programmes to Guy Carpenter risk analyst tracks and Oliver Wyman internships. The biggest strengths are breadth of roles and structured learning language in multiple programmes, paired with stable benefits. The main limits are uneven public signals on candidate experience and outcomes, because Marsh McLennan does not publish conversion rates, retention, or time-to-promotion data for early-career cohorts.
