Machine Learning Engineer Interview Topic Categories

Develops and deploys machine learning models and AI systems to solve complex problems and automate decision-making processes. They bridge the gap between data science research and production implementation of ML solutions. Responsibilities include designing and implementing machine learning algorithms, building and training neural networks and deep learning models, deploying ML models to production environments, optimizing models for performance and scalability, and monitoring model performance in production. They work with ML frameworks like TensorFlow, PyTorch, scikit-learn, cloud ML platforms, and containerization technologies. Daily activities involve developing ML algorithms, training and validating models, implementing model serving infrastructure, conducting A/B testing on model performance, optimizing model accuracy and efficiency, and collaborating with data scientists and software engineers.
