The interview process for a Consultant at Marsh & McLennan is thorough and structured to evaluate candidates across multiple performance dimensions. The overall flow typically progresses from automated digital assessments to live, panel-style discussions with practice leaders and partners.

Initial screening generally begins with either a recruiter phone call or a standardized HireVue video assessment. The recorded session provides short preparation windows before asking candidates to record responses on behavioral and motivational scenarios. Depending on the practice area, candidates may also complete short interactive game assessments designed to evaluate logic, memory, and decision-making styles.

Subsequent stages consist of live interview rounds conducted virtually via Zoom or in-person at regional offices. Candidates usually move into a series of 30-to-45-minute interviews with current consultants, principals, and hiring managers. These rounds combine deep behavioral evaluations with technical discussions, Excel/analytical assessments, and case study presentations. Candidates who reach final rounds often present a prepared business case or participate in back-to-back panel interviews ("Superdays") with senior practice leaders.

The timeline module outlines the standard progression from your initial application through digital screenings, case reviews, and final executive interviews. Candidates should use this roadmap to map out preparation milestones, balancing behavioral story refinement with quantitative case practice. Note that while entry-level and campus recruiting pipelines rely heavily on HireVue assessments, experienced hires may transition faster into direct conversational rounds with practice leaders.

To pass the selection process, candidates must demonstrate strength across several core competencies. Interviewers look for balanced expertise in technical execution, logical structuring, and interpersonal leadership.

You collaborate regularly with internal practice specialists, actuarial teams, subject matter experts, and account managers to ensure engagements are delivered on schedule and within scope.

In addition to direct client work, Consultants contribute to internal practice development. This includes helping draft proposal responses (RFPs), researching market trends, developing proprietary benchmarking databases, and mentoring junior analysts on technical tools and consulting methodologies.
