Analytical Background Questions
The candidate's analytical skills and experience with data driven problem solving, including statistics, data analysis projects, tools and languages used, and examples of insights that influenced product or business decisions. This covers academic projects, internships, or professional analytics work and the end to end approach from hypothesis to measured result.

Implement an efficient Python function `moving_average(iterable, window_size)` that yields the rolling mean for each window. The implementation should use O(1) amortized work per element and O(window_size) space, support arbitrary iterables (not just lists), and handle edge cases (window_size > length, non-numeric values).

Explain what a p-value represents and list three common misconceptions. As an analytics engineer, how would you communicate p-values and statistical significance to product stakeholders making go/no-go decisions on feature launches?

Design a metrics monitoring system that detects regressions after deployments and supplies automated root-cause hints (e.g., by segment/platform). Cover data ingestion for metrics, baseline computations accounting for seasonality, alert thresholds, diagnostic enrichment (segmentation, correlated metrics), and strategies to reduce noisy alerts for on-call engineers.

Explain the bias-variance tradeoff in supervised modeling. Provide practical examples where a product model exhibits high bias vs high variance, describe how you'd detect each using learning curves, and list remediation strategies for both scenarios.

A new recommendation algorithm was rolled out to 20% of users but the rollout was not random (e.g., based on account age). Describe how you'd estimate its causal impact on revenue: identify biases, propose methods (propensity score matching/weighting, regression adjustment, instrumental variables, synthetic controls), required data, diagnostics, and validation checks.
