About the company

Aon is a professional services firm focused on risk, reinsurance, and health and retirement solutions for employers and organisations. Aon’s teams advise clients on insurance and reinsurance placement, risk analytics, employee benefits, retirement strategy, and broader human-capital topics. Aon operates globally, reporting operations in more than 120 countries and a workforce of roughly 60,000 employees. Aon runs its global operational headquarters in London and also has a major North America base in Chicago.

Locations and presence

Aon lists a global operational headquarters in London, a registered office in Dublin, and a major North America base in Chicago, alongside offices across multiple regions. Aon’s early-career programmes commonly start office-heavy (for example, some UK graduate streams ask for the first 6 months in-office, then a hybrid pattern of 3–4 days face-to-face).

Palpable Score

75.1

/ 100

Aon offers multiple real entry routes, including paid internships, graduate Launch pathways, and apprenticeships that are designed for people starting out. Aon also publishes a relatively clear early-career selection journey in public-facing guidance, but candidate experiences suggest timing and communication can still vary by role and location. The score is held back mainly by limited public outcomes data, such as conversion rates from internships to full-time roles and early-career retention or promotion metrics.

Pillar 1: Early-career access

Score

16.7

/ 20

The company runs Launch as a recurring early-career programme for graduates, with a defined 10-month structure in the US and a clear “annual cohort” framing.
Aon offers paid early-career placements across regions, including a 10-week paid US summer internship and UK paid summer internships plus 12-month industrial placements.
The company provides additional access points beyond university hiring, including apprenticeships (UK and US) and a UK Work Insights Programme aimed at school or college students.

Pillar 2: Hiring fairness and transparency

Score

13.9

/ 20

The company outlines a multi-stage recruitment flow publicly (online application, online assessments, video interview, shortlisting, assessment centre, and sometimes a final interview), which helps first-time applicants anticipate what’s coming.
Aon publishes UK Early Careers FAQs that set expectations on assessment-centre windows and start dates, and also offers contacts for reasonable adjustments.
The company has candidate-reported feedback that early stages can feel heavily test-led and slow-moving for some internship applicants, which reduces perceived consistency even when the process is structured.

Pillar 3: Learning and support

Score

16.8

/ 20

The company builds Launch around defined learning inputs (for example, a three-day kickoff orientation in the US and a named “training curriculum” intended to build relationships and growth opportunities).
Aon’s UK graduate streams describe funded professional qualifications with tutorial support, study materials, and study leave, which is practical scaffolding for early-career progression.
The company’s graduate and internship materials repeatedly describe mentorship, learning sessions, and access to senior colleagues as part of the early-career experience, rather than leaving development to informal team-by-team effort.

Pillar 4: Pay fairness and stability

Score

15.0

/ 20

The company explicitly positions US internships as paid and publishes internship pay ranges via third-party job listings that mirror the role’s advertised compensation band.
Aon posts at least some early-career graduate pay in public listings (for example, an Ireland graduate role listed at €35,000) and pairs this with benefits like pension and health cover in programme adverts.
The company often uses “competitive and in line with market rates” language on early-career pages without consistently publishing exact salaries across all streams and countries, which limits transparency for offer comparison.

Pillar 5: Early-career outcomes

Score

12.7

/ 20

The company links early-career programmes to concrete next steps, including internship-to-Launch conversion language and graduate programme pages that describe ongoing promotion pathways after a structured period.
Aon has substantial student and early-career review volume on third-party platforms, with many reviews describing supportive teams and strong learning, which suggests plenty of juniors are getting a positive first-job experience.
The company does not publish outcomes metrics like internship return-offer rates, cohort retention, or time-to-promotion by programme, which makes it hard to judge how predictable the “pipeline” is across offices and streams.
