With the firm operating globally, you can filter by country and city to find roles that match your geographic preferences. Pay close attention to the job descriptions, required qualifications, and preferred skills listed for each position, as these will directly inform how you tailor your resume and cover letter.
2
Create or Log Into Your Workday Candidate Profile
Marsh McLennan uses Workday as its applicant tracking system, so you will need to create a candidate profile to apply. This typically involves entering your contact information, uploading your resume, and filling out supplementary fields such as education history, work experience, and any relevant certifications. Many applicants report that Workday auto-parses resume content into structured fields — it is critical to review these parsed fields carefully and correct any errors, as inaccurate data can negatively affect how your application is evaluated or filtered.
3
Tailor and Submit Your Application Materials
For each role you apply to, customize your resume and any optional cover letter to align with the specific job description. Highlight relevant experience in insurance services, risk management, consulting, financial analysis, or whatever domain the role requires. Use keywords directly from the job posting, as Workday-based systems commonly use keyword matching to help recruiters filter and rank candidates. Ensure your application is complete before submitting — incomplete applications may be deprioritized or automatically screened out.
4
Initial Screening and Recruiter Outreach
After submission, your application will typically be reviewed by a recruiter or talent acquisition specialist. Based on publicly available information and candidate reports, Marsh McLennan's recruitment team commonly conducts an initial phone or video screening to assess basic qualifications, salary expectations, availability, and cultural fit. This stage may also include competency-based questions related to the specific business unit. Be prepared to articulate why you are interested in Marsh McLennan specifically and how your background aligns with the firm's mission of helping clients manage risk.
5
Interview Rounds — Technical and Behavioral
Candidates who pass the initial screening are typically invited to one or more interview rounds. Depending on the role and seniority level, this may include a combination of behavioral interviews, technical assessments, case studies (particularly for Oliver Wyman and consulting-oriented roles), and panel interviews with hiring managers and team members. For roles such as Senior Analyst - FP&A or Controllership positions, expect questions around financial modeling, reporting, and analytical problem-solving. For client-facing roles like Account Management or Insurance Placement Specialists, interviewers commonly assess relationship-building skills and industry knowledge.
6
Final Interview and Offer Stage
Senior-level or specialized positions may involve a final-round interview with a department head or senior leadership. Many candidates report that this stage focuses on strategic thinking, leadership capabilities, and long-term career alignment with the firm.

Resume Tips for Marsh McLennan

critical

Mirror the Language of the Job Description

Workday-based ATS platforms commonly use keyword matching to help recruiters identify strong candidates. Carefully read the job posting and incorporate relevant terms into your resume. For example, if the posting mentions 'risk management,' 'client relationship management,' 'financial planning and analysis,' or 'quality assurance,' use those exact phrases where they truthfully apply to your experience. This increases the likelihood that your resume will surface in recruiter searches within the Workday system.

critical

Quantify Achievements with Metrics

Marsh McLennan operates in a data-driven, results-oriented environment. Rather than listing job duties, frame your experience in terms of measurable outcomes. For instance, instead of 'Managed client accounts,' write 'Managed a portfolio of 45+ commercial insurance accounts totaling $12M in annual premiums, achieving a 95% client retention rate.' Quantified achievements resonate strongly in professional services and demonstrate the kind of analytical rigor the firm values.

critical

Highlight Industry-Relevant Certifications and Education

For insurance and risk management roles, certifications such as CPCU (Chartered Property Casualty Underwriter), ARM (Associate in Risk Management), CFA, or actuarial credentials can significantly strengthen your application. For consulting roles under Oliver Wyman or Mercer, MBA degrees or relevant advanced certifications are commonly valued. Ensure these credentials are prominently displayed in a dedicated section near the top of your resume.

critical

Use a Clean, ATS-Compatible Resume Format

Workday's resume parser works best with standard formatting. Use a simple, single-column layout with clearly labeled section headers (e.g., 'Professional Experience,' 'Education,' 'Skills'). Avoid tables, text boxes, graphics, headers/footers with critical information, and unusual fonts. Submit your resume as a .docx or .pdf file unless the posting specifies otherwise. This ensures the parser accurately extracts your information into the Workday candidate profile fields.

recommended

Demonstrate Cross-Functional and Global Experience

Given Marsh McLennan's global footprint and multi-business structure, candidates who can demonstrate experience working across functions, geographies, or business lines tend to stand out. If you have experience collaborating with international teams, managing cross-border projects, or working in matrixed organizations, highlight this prominently. This is particularly relevant for roles that span multiple Marsh McLennan businesses or require coordination across regions.

recommended

Include a Tailored Professional Summary

Begin your resume with a 3-4 sentence professional summary that positions you specifically for the role you're applying to at Marsh McLennan. Reference the business unit (Marsh, Guy Carpenter, Mercer, or Oliver Wyman) and the specific function. For example: 'Results-driven FP&A professional with 7+ years of experience in financial planning, budgeting, and forecasting within the professional services sector. Seeking to leverage analytical expertise and strategic insight as a Senior Analyst at Marsh McLennan.' This immediately signals relevance to the recruiter.

recommended

Showcase Client-Centric and Relationship Management Skills

Marsh McLennan's business model is fundamentally built on client relationships. Whether you're applying for an insurance placement specialist role, an account management position, or a consulting engagement manager role, emphasize your ability to build and maintain client relationships, manage stakeholder expectations, and deliver client-focused solutions. Use specific examples that demonstrate your client engagement approach and outcomes.

ATS System: Workday

Marsh McLennan uses Workday as its primary applicant tracking and human capital management system. Workday is one of the most widely adopted enterprise ATS platforms globally, used by many Fortune 500 companies. When you apply through the Marsh McLennan careers portal, your resume is parsed by Workday's system, which extracts key information such as job titles, employers, dates of employment, education, and skills into structured data fields. Recruiters can then search and filter candidates using keywords, qualifications, and other criteria within the Workday platform. Understanding how Workday processes applications can give you a meaningful advantage in ensuring your resume is accurately represented in the system.

Always review and correct the auto-parsed fields after uploading your resume — Workday's parser may misinterpret dates, job titles, or company names, and inaccurate fields can cause your application to be filtered out incorrectly.
Use standard section headers like 'Work Experience,' 'Education,' 'Skills,' and 'Certifications' to help Workday's parser correctly categorize your information.
Avoid placing critical information in headers, footers, or text boxes, as Workday's parser may not read content from these areas reliably.
Incorporate keywords from the job description naturally throughout your resume — Workday allows recruiters to search by keywords, and matching terms can improve your visibility in candidate searches.
Submit your resume in .docx or .pdf format for optimal parsing compatibility, and keep formatting simple with standard fonts like Arial, Calibri, or Times New Roman.
If applying to multiple Marsh McLennan roles, tailor your resume for each application rather than submitting the same generic version — Workday tracks applications per requisition, and customized resumes tend to perform better in keyword-based filtering.
