Explain project assumptions and validation methods
Graham CapitalSoftware Engineer · Technical ScreenLast updated
This question evaluates expertise in analytics and experimentation, focusing on formulating project assumptions, selecting validation methods, and managing end-to-end data workflows and model evaluation.
For that project, list your key assumptions and why they were justified. How did you validate each assumption (e.g., EDA, sensitivity analysis, ablations, holdout or rolling out-of-sample tests)? Describe the step-by-step process from data collection to final evaluation, and how you prevented data leakage and overfitting.
