Aon at a glance

• Revenue rank: #279
• Industry: Professional services
• Country / major ops: United Kingdom
• Approx. revenue: $15.7B
• Guide focus: hiring funnel, stages, eligibility, prep plan
• Related guides: interview prep · layoff signals

Around $15.7B in revenue, Aon hiring is still structured: screen for eligibility, validate skills, then behavioral/fit rounds. Smaller employer brand does not mean an unstructured process—candidates still need a clean résumé, a defendable project story, and honest logistics before the offer conversation.

Within Professional services, Aon hiring usually validates role fundamentals early, then ownership and communication before an offer package is discussed. Use the live JD to decide whether your hardest filter is skills, domain, or logistics.

Across United Kingdom, Aon hiring usually adds logistics checkpoints (work authorization, language, notice period) between skills and offer. Confirm remote vs office policy on the live req, and expect longer calendar gaps when works councils or formal offer approvals are involved.

Typical Aon hiring funnel

Exact stages vary by role family (engineering, ops, corporate, GTM). A common pattern for Professional services employers like Aon:

1. Application screen — résumé + eligibility
2. Skills / assessment round — role-specific problems
3. Behavioral / panel — ownership and fit for Aon
4. Offer & onboarding logistics

Always confirm the live job posting and recruiter brief for Aon—process order can change by country and business unit. Use this page as a map, then customize from the req.

What each stage is testing (quick checklist)

• Screen: match the posting’s must-haves
• Skills: one project you can defend end-to-end
• Behavioral: two STAR stories (impact + conflict)
• Offer stage: know your constraints before negotiating

Stage-by-stage: how to clear the Aon funnel

Application screen

Match the posting’s must-haves. Tailor one Aon-aligned résumé rather than sending a generic file to every business unit. Use the ATS checker to catch keyword gaps.

Skills / assessment

Bring one project you can defend end-to-end: problem, constraints, your decisions, measurable outcome, and what you would change. That story often carries more weight than a long tool list.

Behavioral / panel

Prepare at least two STAR stories (impact + conflict). Panels at Aon-scale employers punish vague “we did” language—own your slice of the work. The STAR Answer Builder helps structure answers before mock practice.

Offer and logistics

Know notice period, relocation, and compensation constraints before the final conversation. Late surprises create friction even after strong interviews.

Campus vs lateral vs experienced hiring at Aon

The same employer brand can hide different funnels:

If you are switching industries into Professional services, map which Aon track you are actually in before you copy a friend’s prep plan. A campus OA sprint will not prepare a lateral panel loop—and vice versa.

Timeline expectations for Aon

Across United Kingdom, Aon funnel length depends on track and approvals. Campus and volume hiring compress stages; lateral and leadership hiring stretch them. Treat the recruiter’s stated timeline as the plan, then build buffer for background checks and offer letters.

How to read a Aon job posting before you apply

Treat the live Aon req as the funnel contract:

1. Must-haves vs nice-to-haves — degree, years, tools, licenses, location
2. Role family — engineering, ops, GTM, finance, people, etc. (this chooses your skills gate)
3. Level signals — senior/staff language usually means fewer OAs and deeper ownership panels
4. Location and work mode — hybrid/onsite/remote rules that will appear in HR
5. Keywords — mirror them honestly on your résumé, then verify with the ATS checker

If the posting is thin, ask the recruiter for round order after you apply. Do not invent a Aon process from social media threads.

Questions to ask Aon recruiters (process clarity)

Use these after a screen clears—or in the first recruiter call:

• What are the remaining stages for this Aon req, and who owns each stage?
• Is there an OA, take-home, or live skills round for this track?
• Typical calendar time from this stage to offer for similar Professional services roles?
• Any hard constraints on location, shifts, travel, or start date I should know now?
• How should I prepare differently for campus vs lateral loops at Aon?

Clear answers save days of misdirected prep. Vague answers mean you should lean harder on the posting and the Aon interview preparation guide for skill practice.

Eligibility and logistics checklist

Before you enter mid-funnel rounds at Aon, confirm:

• Degree, experience, location, and work-authorization rules on the posting
• Notice period and relocation constraints you can defend in HR
• One ATS-clean résumé aligned to the req (ATS checker)
• Two STAR stories ready for behavioral panels (STAR Answer Builder)
• A specific “Why Aon / why this business unit?” answer—not a generic brand compliment

Prep plan once you understand the funnel

For interview-day tactics (what to practice live), see the companion Aon interview preparation guide and the company interview guides hub.

Common Aon funnel mistakes

• Treating every Aon req as the same process across campus, lateral, and leadership tracks
• Skipping the OA/skills gate because “I’ll wing the interview”
• Surprising HR late with location, notice, or authorization constraints
• No timed practice before multi-round days
• Memorizing Aon trivia instead of rehearsing structured problem-solving
• Sending one generic résumé to every Professional services posting under the Aon brand

After you clear interviews: offer hygiene

Clearing the Aon hiring process is not the finish line. Before you accept:

1. Confirm role level, team, and location in writing
2. Align start date with your notice period and any background-check lead time
3. Decide your walk-away constraints before compensation talks
4. If you are comparing employers for stability as well as offer strength, run the free layoff signals tool and read the Aon layoff signals guide

Application volume strategy for Aon-scale employers

Applying to Aon is rarely a single-click event:

• Quality over spray — one tailored résumé per role family beats ten generic uploads
• Track stages — spreadsheet the req link, apply date, recruiter name, and next expected stage
• Parallel peers — when Aon timelines stretch, keep practicing with peer funnels from the hiring guides hub and interview drills from the interview guides hub
• Reuse practice, not résumés — STAR stories and timed mocks transfer; keyword soup does not
• Stay current — if a Aon req is reposted or the business unit reorgs, re-read eligibility before your next round

Candidates who treat the Aon hiring process as a project—with artifacts, timelines, and rehearsal—outperform candidates who only “wait for HR to email.”

Red flags vs green flags while you are in the Aon funnel

Green flags (process health): clear stage list from the recruiter, predictable follow-ups, written confirmation of next steps, interviewers who have read your résumé.

Yellow flags: long silence after a strong round without a stated SLA, last-minute panel changes, conflicting descriptions of the role level.

Red flags (for your decision-making, not panic): unpaid “trial work” that looks like free consulting, pressure to resign before a written offer, or refusal to state whether the req is still funded.

None of these replace your judgment. If you are weighing whether to keep investing energy in Aon versus other employers, combine process clarity with the educational Aon layoff signals guide and peer funnels on the hiring guides hub.

What “prepared” looks like before your next Aon stage

Before each upcoming round, you should be able to answer yes to:

• I know which stage is next and what it usually tests at Aon
• My résumé matches this req’s keywords (ATS checker)
• I can deliver two STAR stories in ~90 seconds each (STAR builder)
• I have done at least one timed rehearsal for the skills gate (how it works / Aon interview prep)
• My logistics (notice, location, authorization) will not surprise HR
• I have one thoughtful question for the interviewer or recruiter

If any item is still “no,” fix that before you ask for more referrals into Aon.

Frequently asked questions

Is the Aon hiring process the same worldwide?

No. Country, business unit, and role family change stage order and tools. Use the posting for that Aon req as source of truth, then ask the recruiter to confirm the expected sequence.

How long does the Aon funnel take?

Campus drives can finish in days; lateral loops often take weeks. Recruiter SLAs vary—ask for the expected timeline after each clear stage, especially in United Kingdom.

Where do most candidates drop off?

Usually the skills gate (OA or first technical/case round). Practice under time pressure before you enter that stage, then rehearse spoken structure for later interviews via the Aon interview prep guide.

Do I need different prep for campus vs lateral Aon roles?

Yes. Campus tracks are often OA-heavy and compressed; lateral tracks weight ownership stories and multi-round panels. Match your plan to the track in the posting.

What should I put on my résumé for Aon?

Role-matched keywords, quantified impact, and one project you can defend end-to-end. Run an ATS check before applying widely across Professional services postings.

How do I prepare behavioral answers for Aon?

Use STAR (situation, task, action, result) with your personal contribution clear. Draft with the STAR Answer Builder, then rehearse out loud in timed mocks (how ClavePrep works).

Should I worry about layoffs while applying to Aon?

Job-security signals are separate from hiring-process prep. If you want an educational checklist, use the Aon layoff signals guide and the layoff guides hub—not rumors threads.

Can ClavePrep help with the Aon hiring process?

Yes—timed AI mocks help you rehearse the interview stages of the funnel after you understand stage order. Start with how ClavePrep works, and browse more employers on the hiring guides hub.
