This category evaluates why you want to join Aon and whether you understand the realities of a client-facing advisory career.

• What makes you want to work at Aon?
• What motivations do you have for this specific Consultant role?

Preparing effectively for your upcoming discussions requires a balanced approach that pairs your technical background with structured communication. Interviewers at Aon look for individuals who can deconstruct ambiguous problems, communicate recommendations with clarity, and demonstrate genuine commercial awareness.

Role-related knowledge – This criterion measures your technical and domain expertise, whether in retirement schemes, health benefits, insurance, or financial reporting. Interviewers evaluate your familiarity with industry regulations, analytical frameworks, and tools like Excel and SQL. You can demonstrate strength here by staying updated on macroeconomic trends and articulating how market shifts impact client portfolios.

Problem-solving ability – This assesses how you approach unstructured challenges, guesstimates, and analytical cases. Interviewers want to see a methodical breakdown of a problem, logical assumptions, and sound quantitative reasoning. You can stand out by talking through your thought process out loud and validating your hypotheses before diving into calculations.

Leadership and collaboration – This evaluates your interpersonal dynamics, teamwork, and ability to influence others without formal authority. In group exercises and behavioral interviews, your capacity to include peers, manage friction, and lead through consensus is closely scrutinized. Highlight experiences where you brought cross-functional teams together or navigated complex stakeholder negotiations.

Culture fit and resilience – This explores your alignment with Aon values, your ability to handle stress, and your stamina for a client-driven environment. Interviewers test your resilience through rapid-fire questioning, stress scenarios, and behavioral probes about high-pressure deadlines. Showcase your adaptability, emotional intelligence, and genuine enthusiasm for solving complex human and business challenges.

The interview process at Aon is comprehensive, professional, and designed to evaluate both your technical acumen and your consulting potential. Depending on the region and business line, the journey typically begins with an online application followed by digital assessments and a pre-recorded or one-way video interview. These initial stages test your cognitive abilities, written communication, and baseline motivations, often featuring timed responses and multiple-choice scenarios.

This visual timeline illustrates the typical progression from initial screening all to the way to final panel or partner interviews. Candidates should use this roadmap to pace their preparation, ensuring they are ready for both automated digital assessments and intensive live interactions. Keep in mind that specific business lines—such as retirement consulting or catastrophe modeling—may incorporate assessment centres featuring group exercises and written business cases.

Candidates should manage their energy carefully across the multiple stages, maintaining the same level of enthusiasm for early recruiter calls as they do for senior partner panels. The interview philosophy emphasizes collaboration over raw interrogation, meaning that interviewers will look closely at how you interact, listen, and respond to feedback. Treat every stage as a two-way dialogue to assess your potential future teammates.

Technical and Domain Expertise

This evaluation area measures your foundational knowledge of your chosen advisory vertical, such as defined benefit plans, investments, insurance markets, or financial accounting. Interviewers want to verify that you can hit the ground running with standard industry frameworks and regulatory environments. Strong performance involves not only knowing definitions but applying them directly to hypothetical client scenarios.

Be ready to go over:

• Pension and investment fundamentals – Defined benefit versus defined contribution structures, regulatory processes, and asset allocation strategies.
• Risk modeling and insurance concepts – Catastrophe modeling, reinsurance principles, and risk assessment methodologies.

As a Consultant at Aon, your day-to-day work revolves around solving complex client problems and delivering high-impact strategic recommendations. You will spend a significant portion of your time analyzing data, building financial models, and drafting reports that translate dense regulatory or market information into clear executive summaries. Your deliverables directly support client decision-making across employee benefits, risk management, executive compensation, and investment portfolios.

Collaboration is central to your daily routine. You will work closely with internal specialists—such as actuaries, data scientists, and account managers—to synthesize inputs and ensure holistic project delivery. When preparing for client pitches or annual reviews, you contribute to proposal development, respond to RFPs, and participate in client meetings. This requires you to manage multiple workstreams simultaneously, balancing long-term strategic projects with urgent client requests.

Ultimately, you act as an owner of your deliverables. You are expected to take initiative, anticipate client needs, and maintain rigorous attention to detail in every calculation and slide deck. By combining technical analytical rigor with strong relationship management, you help build the long-term trust that defines Aon’s market reputation.

Meeting the qualifications for a Consultant role at Aon requires a blend of analytical horsepower, relevant industry experience, and polished communication skills. While specific technical requirements vary by team—such as deep pensions knowledge for retirement roles or catastrophe modeling expertise for risk roles—certain core competencies are universally expected.

• Must-have skills – Proven experience in a client-facing, analytical, or advisory capacity; strong quantitative and problem-solving abilities; advanced proficiency in spreadsheet tools like Excel; and exceptional written and verbal communication skills.
• Nice-to-have skills – Prior experience with SQL or data visualization tools; professional certifications relevant to your vertical (such as actuarial exams, CFA, or specialized risk designations); and familiarity with RFP responses or business development processes.
• Experience level – Typically requires several years of progressive professional experience in consulting, financial services, insurance, or corporate strategy, paired with a relevant undergraduate or advanced degree.
• Soft skills – High emotional intelligence, resilience under pressure, the ability to collaborate in multidisciplinary teams, and a demonstrated talent for explaining complex technical topics to non-technical audiences.

• Structure your behavioral stories: Use the STAR method to organize your responses to situational and competency questions, ensuring you clearly articulate your personal actions and the ultimate impact.
