Travelers Insurance·Data Scientist·Technical Phone Screen
Jul 2026
Technical phone screen for a data scientist role at Travelers Insurance, heavy on stats fundamentals. One long question about multicollinearity that basically asked you to know everything at once. Felt more like a written exam than a conversation.
- You're building an interpretable model like logistic regression for an insurance company where several input features are highly correlated. Walk through what multicollinearity is, how it affects your model's coefficients and interpretability, whether it hurts prediction vs. inference differently, how you'd detect it, and what you'd do about it during feature selection and modeling.
“This was a lot to hold in your head at once.”
