Implement a mini training pipeline in PyTorch for a pairwise learning-to-rank model for sessions: describe dataset format (user, positive_item, negative_item), negative sampling strategy, loss function (e.g., pairwise hinge or logistic), and a simple training loop pseudocode that addresses efficiency when there are millions of items.

Cold-start problem for new titles: propose a practical Netflix-oriented strategy to recommend newly added titles with zero user interactions. Include feature sources (metadata, posters, trailers, cast), modeling approaches, offline experiments to validate, and an online rollout plan with guardrails.

Design a production monitoring plan for a deployed video-quality prediction model that estimates expected buffering probability per stream. Include model metrics to monitor (statistical and business), drift detection methods, alerting thresholds, and suggested remediation steps when the model degrades.

Design a simple composite engagement score for Netflix that combines normalized watch_time, completion_rate, thumbs_up_count, and search_interactions into a single number between 0 and 100 for each user-week. Describe your normalization method, how you would choose weights, how you would handle outliers and missing data, and one objective test to validate that the score correlates with retention.
