This question assesses your understanding of mathematical modeling, a critical skill for an actuarial mathematician, and your ability to apply theoretical concepts to practical situations.
How to answer
- Start by briefly explaining the mathematical model, including its purpose and components.
- Discuss the context in which you applied this model, highlighting any data or assumptions used.
- Explain the results or insights gained from the model and how they could be applied in a real-world setting.
- Mention any challenges you faced during the modeling process and how you overcame them.
- Conclude with what you learned from this experience and how it has prepared you for the role.
What not to say
- Describing a model without explaining its relevance or application.
- Failing to include specific details about the model or the data used.
- Overcomplicating the explanation with unnecessary jargon.
- Not acknowledging any limitations of the model or the results.
Sample answer
“During my studies, I developed a predictive model for evaluating the risk of car insurance claims based on historical data. I used a logistic regression model to analyze factors such as age, driving history, and vehicle type. This model helped identify high-risk profiles, allowing insurers to adjust premiums accordingly. I faced challenges in data cleaning but learned valuable lessons about the importance of accuracy in data analysis. This experience reinforced my interest in applying mathematical concepts to real-world actuarial problems, preparing me for a role at Aviva.”
