Interview questions [2]
Question 1
Question: Five pirates discover a chest containing 100 gold coins. They decide to sit down and devise a distribution strategy. The pirates are ranked based on their experience (Pirate 1 to Pirate 5, where Pirate 5 is the most experienced). The most experienced pirate gets to propose a plan and then all the pirates vote on it. If at least half of the pirates agree on the plan, the gold is split according to the proposal. If not, the most experienced pirate is thrown off the ship and this process continues with the remaining pirates until a proposal is accepted. The first priority of the pirates is to stay alive and second to maximize the gold they get. Pirate 5 devises a plan which he knows will be accepted for sure and will maximize his gold. What is his plan?
Competency questions: work in a team, time when there was disagreement, explain in plain words something that is highly technical; why this role why Aon? Prepare for all the questions on Glassdoor and it will be enough
The recruitment process has three stages. First is the initial application. Next is the video AI interview. The final stage is the in person Assessment Centre. This means the overall process is shorter compared to some other companies that have more interview stages.
I applied online. The process took 1+ week. I interviewed at Aon (Peterborough, England) in Dec 2025
Interview
There was a video Interview, one motivation and 3 behavioural questions. The behavioral questions are a bit different from what you see in other companies. The interview is conducted on the hirevue platform.
There involved a psychometric assessment. Following this I was invited to an online assessment centre. This involved a two group tasks and a one to one interview. Overall the assessment centre was good.
