About the company

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.

/ 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.
