How to Pass the Aon IB Analyst Interview in 2026
The Aon DNA (TL;DR)
Aon's client-facing roles often require candidates to articulate complex risk solutions clearly. Interviewers assess your ability to structure arguments and present insights, often through case studies or discussions about past project 'TIMELINE's, emphasizing logical flow and impact.

Your onsite loop will typically consist of 4 rounds.

The Danger Zone: Top Reasons Candidates Fail
Based on our database of Aon interview outcomes, avoid these common traps:
- Focusing solely on compensation or prestige without demonstrating genuine interest in the work.
- Focusing only on winning the argument rather than finding a collaborative solution.
- Confusing the components of each (e.g., including minority interest in Enterprise Value).
- Describing a situation that was easily resolved without demonstrating significant effort or skill.
