Example questions or scenarios:

• "A client's average compa-ratio is 1.15, but their turnover remains high. How would you investigate this anomaly?"

Behavioral & Consultative Communication

As a specialist in a consulting firm, you must be able to collaborate with internal client teams and present your findings in a persuasive, easy-to-understand manner.

Be ready to go over:

• The STAR Method – Structuring your behavioral answers by defining the Situation, Task, Action, and Result.
• Stakeholder Management – Handling situations where clients or senior colleagues challenge your data or conclusions.
• Prioritization – Managing multiple client deliverables simultaneously without sacrificing data quality.

Example questions or scenarios:

• "Tell me about a time when you had to present data that delivered bad news to a client or manager. How did you handle the conversation?"
• "Describe a situation where you had to collaborate with a difficult team member to complete an analytics project."

Once the objectives are set, you will be responsible for gathering data from clients, ensuring its quality and consistency, and performing the necessary statistical analyses. You will translate these findings into clean, client-ready presentations and reports that clearly articulate the business implications of the data.

Additionally, you will contribute to the continuous improvement of the team's analytical capabilities. This includes developing standardized templates, exploring new analytics tools, and staying up-to-date with industry trends in HR metrics and labor market regulations in France. Your role is vital in ensuring that Mercer remains at the cutting edge of data-driven workforce consulting.

It involves multiple stages, including online assessments, technical tests, and interviews with senior leadership, so maintaining proactive communication with your recruiter is highly recommended.
