Curiosity and Investigative Problem Solving Questions
Assess intellectual curiosity and investigative habits: asking why, digging into root causes, exploring alternatives, and demonstrating enthusiasm for learning how systems work. Candidates should show evidence of proactively researching problems, asking good follow up questions, and a mindset of continuous improvement. This topic captures behavioral indicators that predict thoroughness and long term growth potential.

Provide a step-by-step statistical procedure to test whether training and production data distributions differ across many high-dimensional features. Include dimensionality reduction or feature selection, multivariate tests, per-feature importance for drift, and guidance on interpreting p-values and effect sizes in production monitoring.

During training you observe a sharp spike in validation loss at epoch 10 that then returns to the prior curve. Lay out how you'd investigate whether this represents a true model issue, noisy measurements, or a transient data problem. Include reproducibility checks and experiments to run.

You have a fixed compute budget and need to test 10 different model architectures. Propose an efficient experiment design (e.g., multi-fidelity, progressive resizing, Hyperband, Bayesian search) and explain stopping criteria and trade-offs between exploration and cost.

You suspect feature leakage inflated offline results. Design a set of tests to detect leakage, including how to instrument the training pipeline, simulate production timing constraints, and validate causal ordering of features to ensure no future information is used at training time.

Your model exposes feature attributions but leadership wants concise root-cause explanations for errors in several high-value transactions. Describe how you'd combine explainability tools (SHAP, LIME, counterfactuals) with investigative steps (request logs, feature snapshots, label audits) to produce an executive-facing, actionable report.
