Comprehensive AI/ML and LLM interview questions covering fundamental concepts, algorithms, and practical applications.

AI/ML Fundamentals

Interview questions covering core machine learning concepts, algorithms, and best practices:

  • Easy: Supervised/unsupervised learning, overfitting, bias-variance tradeoff, basic algorithms
  • Medium: Backpropagation, ensemble methods, SVMs, dimensionality reduction
  • Hard: Attention mechanisms, Transformers, VAEs, GANs

LLM & Agentic AI

Interview questions focused on Large Language Models and agent-based AI systems:

  • Easy: What are LLMs, prompt engineering, temperature, agents, RAG
  • Medium: ReAct agents, advanced RAG, agent memory, tool calling
  • Hard: Multi-agent systems, production optimization, advanced architectures

All examples include LangChain implementations and Mermaid diagrams for visual explanations.
