Machine Learning & AI Topics
Production machine learning systems, model development, deployment, and operationalization. Covers ML architecture, model training and serving infrastructure, ML platform design, responsible AI practices, and integration of ML capabilities into products. Excludes research-focused ML innovations and academic contributions (see Research & Academic Leadership for publication and research contributions). Emphasizes applied ML engineering at scale and operational considerations for ML systems in production.
Artificial Intelligence and Machine Learning Progression
Personal career narrative focused on progression within artificial intelligence and machine learning domains toward senior or staff level roles. Candidates should highlight domain specific milestones such as research contributions, production AI systems designed or architected, scale and complexity of models and pipelines, leadership of ML initiatives, cross functional influence on product or infrastructure, publications or patents if applicable, and how technical depth and organizational impact grew over time. Include concrete examples of projects, measures of system performance or business impact, and how domain expertise informs readiness for advanced technical leadership roles.
Airbnb AI/ML Applications and Product Vision
Airbnb-specific discussion of how AI/ML capabilities are developed and applied across Airbnb's product portfolio, including practical deployment considerations, ML architectures, experimentation, product strategy, and governance for ML-enabled features (search, pricing, recommendations, image recognition, fraud detection, and user experience improvements). Emphasizes real-world machine learning systems in production and alignment with product strategy.
Model Architecture Selection and Tradeoffs
Deals with selecting machine learning or model architectures and evaluating relevant tradeoffs for a given problem. Candidates should explain how model choices affect accuracy, latency, throughput, training and inference cost, data requirements, explainability, and deployment complexity. The topic covers comparing architecture families and variants in different domains such as natural language processing, computer vision, and tabular data, for example sequence models versus transformer based models or large models versus lightweight models. Interviewers may probe metrics for evaluation, capacity and generalization considerations, hardware and inference constraints, and justification for the final architecture choice given product and operational constraints.
AI and Machine Learning Background
A synopsis of applied artificial intelligence and machine learning experience including models, frameworks, and pipelines used, datasets and scale, production deployment experience, evaluation metrics, and measurable business outcomes. Candidates should describe specific projects, roles played, research versus production distinctions, and technical choices and trade offs.
AI System Scalability
Covers designing and operating machine learning systems to handle growth in data volume, model complexity, and traffic. Topics include distributed training strategies such as data parallelism, model parallelism, and pipeline parallelism; coordination and orchestration approaches like parameter servers, gradient aggregation, and framework tools such as PyTorch distributed, Horovod, and TensorFlow strategies; data pipeline and I O considerations including sharding, efficient formats, preprocessing bottlenecks, streaming and batch ingestion; serving and inference scaling including model sharding, batching for throughput, autoscaling, request routing, caching, and latency versus throughput tradeoffs. Also includes monitoring, profiling, checkpointing and recovery, reproducibility, cost and resource optimization, and common bottleneck analysis across network, storage, CPU preprocessing, and accelerator utilization.
Cloud Machine Learning Platforms and Infrastructure
Knowledge of cloud hosted machine learning and artificial intelligence platforms and the supporting infrastructure used to develop, train, deploy, and operate models at scale. Candidates should be familiar with major managed offerings such as Amazon SageMaker, Google Cloud artificial intelligence platform, and Microsoft Azure Machine Learning and understand capabilities including pretrained models, managed training jobs, managed inference endpoints, model registries, and managed pipelines. Key areas include differences between cloud and local training, distributed and hardware accelerated training options, cost trade offs including spot and preemptible instances, serving patterns such as serverless inference, hosted endpoints and batch processing, autoscaling strategies for inference, model versioning and rollout strategies including canary and blue green deployments, integration with data storage, feature stores and data pipelines, and model monitoring, logging and drift detection. Candidates should also be able to explain when to use managed services versus self hosted or on premises solutions, discussing trade offs around productivity, operational overhead, control and customization, vendor lock in, security, data residency and compliance, as well as operational practices such as continuous integration and deployment for models, testing and validation in production, observability and cost optimization.
