If you'd like to dive deeper into a specific system, I can help you:

“Design a search ranking system for YouTube.”

Candidate Generation (Retrieval): Use lightweight models or heuristic filters (e.g., collaborative filtering, vector database search with HNSW) to reduce billions of posts down to ~100-500 relevant candidates.

: Focus on data collection, ingestion, and labeling.

In the brutal landscape of 2024-2025 tech interviews, a new bottleneck has emerged. Software engineers have memorized LeetCode. They have mastered the "Cracking the Coding Interview" checklist. But then comes the dreaded round.

How does the business goal translate to an ML problem? (e.g., binary classification, ranking, regression).

How the model ingests a user request, fetches features, scores candidates, and returns a response. Step 3: Deep Dive Component Design
