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.

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 inherit a codebase with nondeterministic model outputs and no tests. Prioritize what you would fix first to build a reproducible pipeline (data versioning, fixed seeds, environment pinning, CI tests, model checkpoints) and explain why.

Monitoring alerts that a commonly used feature's distribution has shifted since training. Design a step-by-step investigation to determine if this drift causes model degradation, describing statistical tests, visualizations, sample sizes needed, and how you'd prioritize fixes.

You suspect adversarial or intentional behavior is causing a spike in model errors. Design an investigative workflow to detect, attribute, and mitigate adversarial inputs in production. Include monitoring signals, anomaly detectors, red-team exercises, validation datasets, and automated defense strategies.

When an experiment or training job fails, what is your standard reproducibility and sanity-check checklist you run first (e.g., data checks, environment, random seeds, hyperparameters, metrics). List the top 6 checks and why they matter in an ML context.
