- Choose a specific model that you have worked on, like a linear regression or time series model.
- Describe the purpose of the model and its relevance to a particular problem or dataset.
- Explain the methodology you used in detail, including any assumptions made.
- Discuss the results and their implications for the stakeholders involved.
- Emphasize any challenges faced during the modeling process and how you overcame them.
What not to say
- Using overly technical jargon without explanation.
- Failing to provide context on the model's application.

Sample answer
“In my internship at DBS Bank, I worked on a linear regression model to forecast loan defaults. I collected historical data on customer demographics and payment history, ensuring to check for multicollinearity. The model revealed that income stability was a significant predictor of defaults. By presenting this to the risk management team, we adjusted our lending criteria, which reduced default rates by 15%. This experience taught me the importance of clear communication and the real-world impact of econometric analysis.”
