Excel & Data Manipulation

Excel remains a primary tool for day-to-day data tasks in this role. You will likely face a timed, hands-on Excel assessment designed to test your efficiency and accuracy under pressure.

Be ready to go over:

• Data Cleaning – Using text-to-columns, removing duplicates, and handling blank or erroneous cells within a workforce dataset.

As a People Analytics Specialist at Marsh & McLennan, your day-to-day work will revolve around maintaining data integrity, generating actionable insights, and supporting strategic talent initiatives. You will work closely with HR business partners, compensation specialists, and business unit leaders to ensure that the firm's talent decisions are backed by robust data.

A significant portion of your responsibilities will involve designing, building, and maintaining standard reports and interactive dashboards. These tools allow HR leaders to monitor key metrics such as headcount growth, turnover rates, diversity demographics, and compensation competitiveness in real time.

Additionally, you will participate in ad-hoc analytical projects. For example, during annual compensation planning cycles, you will help model salary increase budgets, analyze market benchmark data, and identify pay anomalies. Your ability to collaborate effectively with global, cross-functional teams will be essential, as you will regularly pull data from centralized systems like Workday and translate it for localized business needs.

The ideal candidate for this role possesses a strong analytical mindset combined with excellent interpersonal skills. Marsh & McLennan looks for professionals who can maintain absolute confidentiality while handling sensitive employee data.

• Must-have skills – Advanced proficiency in Microsoft Excel (including lookups, logical statements, and pivot tables), a solid understanding of descriptive statistics, and familiarity with core HR metrics and compensation terminology.
• Nice-to-have skills – Experience working with HR Information Systems (such as Workday), data visualization tools (like Tableau or Power BI), or basic programming languages used for data analysis (such as SQL or R).
• Experience level – Typically requires 1 to 3 years of experience in data analysis, human resources, compensation, or a related business analyst role. A bachelor's degree in business, statistics, human resources, or a quantitative field is highly preferred.
• Soft skills – Exceptional attention to detail, strong verbal and written communication skills, the ability to work independently under tight deadlines, and a collaborative mindset suitable for a global corporate environment.

Q: How technical is the Excel assessment during the interview process? The Excel test is practical and focuses on standard corporate data tasks. You will be expected to write formulas like SUMIF, AVERAGEIF, and LOOKUP to clean and analyze a mock HR dataset within a 30 to 45-minute window. You should also be prepared to explain your analytical methodology and thought process afterward.

Q: What is the company culture like at Marsh & McLennan? The culture is highly professional, collaborative, and corporate. Because Marsh & McLennan is a global leader in professional services, there is a strong emphasis on quality, accuracy, and clear communication. Team members are generally welcoming and supportive, though the pace can be fast during key business cycles.

Q: How long does the entire hiring process take? The hiring process typically takes between 2 weeks and 2 months from your initial application to an offer. The timeline can vary depending on the location, the specific business unit, and the alignment of senior stakeholders for the final Super Day interviews.

Q: Do I need prior experience in Human Resources to apply? While prior experience in HR or compensation analytics is highly beneficial, it is not always a strict requirement. Strong analytical professionals with transferable data skills, a solid grasp of statistics, and a demonstrated interest in talent strategy are often highly competitive candidates.

To maximize your chances of securing an offer, keep these practical, insider tips in mind as you prepare for your interviews.

Understanding how these operating companies interact and what services they provide will show interviewers that you have done your homework and are genuinely interested in the firm.
• Master the STAR Method: For all behavioral questions, structure your answers clearly. Focus on the specific actions you took and quantify the results whenever possible (e.g., "reduced data processing time by 15%" or "identified a 5% budget discrepancy").
• Test Your Technology Early: Since many rounds are conducted virtually or through asynchronous platforms like HireVue, ensure your camera, microphone, and internet connection are working perfectly well ahead of time.

• Brush Up on Compensation Basics: Even if you do not have a background in compensation, take some time to learn basic terms like salary ranges, market midpoints, and compa-ratios. Demonstrating this domain knowledge will set you apart from candidates with purely general analyst backgrounds.
