Interview Question Bank

Machine Learning Engineer System Design hard

Design the recommendation system for YouTube Shorts. Specifically, how would you handle the cold-start problem for new creators and optimize for real-time engagement metrics like watch time and swipe-aways?

#Recommendation Systems #Two-Tower Models #Cold Start #Real-time Streaming
Machine Learning Engineer System Design hard

Design a system to predict Ad Click-Through Rate (CTR) for Google Search. How do you handle categorical features with massive cardinality, and how do you update the model with fresh data throughout the day?

#CTR Prediction #Feature Engineering #Continuous Training #Embeddings
Machine Learning Engineer System Design hard

Design an autocomplete/typeahead system for Google Docs using a neural language model. The system must run within strict latency constraints (<50ms). How do you optimize the model and serving infrastructure?

#Low Latency Serving #Model Quantization #Sequence-to-Sequence #Edge ML
Machine Learning Engineer System Design medium

Design a system to detect policy-violating images (e.g., hate speech, extreme violence) uploaded to Google Drive. The system must process millions of images per minute with extreme precision to avoid false positives on user data.

#Computer Vision #High Throughput #Active Learning #Anomaly Detection
