The questions below represent common themes observed in recent interviews. While specific technical questions depend on your business unit, you should prepare for a blend of behavioral, situational, and role-specific inquiries.

Motivation and Fit

These questions assess your genuine interest in the firm, your understanding of the Consultant role, and your long-term career alignment.

• Why do you want to work at Willis Towers Watson?
• What specifically excites you about this Consultant role?

Success at Willis Towers Watson requires a balance of technical competence and professional polish. Your preparation should be structured to showcase both your analytical mind and your ability to act as a trusted advisor to clients.

Role-Related Knowledge – You must demonstrate a clear understanding of the specific business line you are applying to, whether it is Actuarial, Risk, or HR Consulting. Research the specific industry challenges, regulatory environments (like IFRS or Solvency II), and the core services Willis Towers Watson provides to its clients.

Problem-Solving Ability – Interviewers look for how you deconstruct a problem. When faced with case studies or Fermi-style estimation questions, focus on your logic, your assumptions, and your ability to structure an answer clearly, even if you do not reach the "perfect" numerical answer.

Leadership and Communication – As a Consultant, you will be expected to manage client relationships and lead project workstreams. Demonstrate your ability to influence others, communicate complex data in simple terms, and take ownership of your tasks.

Culture Fit and Values – Willis Towers Watson values professionals who are collaborative, intellectually curious, and resilient. Be prepared to discuss how you navigate ambiguity and work within diverse, high-performing teams.

The recruitment process at Willis Towers Watson is typically thorough and designed to evaluate candidates across multiple dimensions, including technical skill, logic, and behavioral alignment. You will likely encounter a screening phase—often involving a HireVue video interview and online assessments—followed by a series of live interviews with managers and senior leaders. Depending on the seniority and location, this may also include a Business Case or a technical assessment (e.g., an Excel test or a presentation).

Expect the pace to vary. While some candidates experience a smooth, quick process, others may face a longer timeline with multiple rounds of panel interviews. The company emphasizes a professional, albeit sometimes formal, approach to hiring. Be prepared for a high level of rigor; the firm looks for consistency in your performance across all stages.

The visual timeline shows the progression from initial screening to final-round interviews. Candidates should use this as a roadmap to pace their preparation, ensuring they are ready for the technical hurdles (like Excel or case studies) early on, while keeping their behavioral narratives sharp for the final-stage leadership interviews.

Technical and Quantitative Proficiency

This is the baseline for most Consultant roles. You are expected to demonstrate proficiency in data manipulation and logical reasoning.

• Excel Competency – Be ready for tests that require specific functions or logic application.
• Analytical Thinking – Ability to interpret graphs, charts, and financial data.
• Problem Decomposition – Breaking down large, ambiguous questions into smaller, manageable parts.

Collaboration is central to this role. You will interact with different departments to gather the information needed to solve client problems. You are not just a "number cruncher"—you are expected to provide insights that help the client make better business decisions. Whether you are working on climate risk analysis or compensation benchmarking, your work will directly influence the strategic direction of the companies Willis Towers Watson serves.
