AI Engineering Interview Questions and Answers

About This Interview Question Collection

AI Engineering Interview Questions and Answers is a single README listing interview questions under headings like LLM Fundamentals, Prompt Engineering, Retrieval-Augmented Generation, and AI Agents and Agentic Systems. It's a study map, not a course. Many questions link to Amit Shekhar's YouTube videos, blog posts, or social threads instead of answering inline, and the README says new questions get added over time.

Target Audience for This Guide

This fits engineers actively interviewing for AI-heavy roles: the README lists AI Engineer, Gen AI Engineer, LLM Engineer, Agentic AI Engineer, AI Agent Engineer, Forward Deployed Engineer, AI Solutions Architect, AI Platform Engineer, Applied AI Engineer, MLOps Engineer, and LLMOps Engineer as the roles it's aimed at. It suits someone who already has some ML background and wants a checklist of topics to brush up on before a screen, not someone starting from zero on what a transformer is. This is a reference list, not a curriculum. Skip it if you want a self-paced course with graded exercises.

Core AI Engineering Topics Explored

• ✓The 'Must Know' quick list (LLM, RAG, MCP, Agent, Fine-tuning, Quantization) anchored to a single overview video covering all six topics.
• ✓An LLM Fundamentals section that digs into transformer internals: tokenization and BPE, self/cross/multi-head attention, positional encoding and RoPE, KV cache, Mixture of Experts, Flash Attention, and RMSNorm.
• ✓A Prompt Engineering section spanning zero-shot, one-shot, and few-shot prompting, chain-of-thought and ReAct prompting, prompt injection defense, and structured-output design.
• ✓A Retrieval-Augmented Generation section on chunking strategies, embedding model choice, hybrid search, re-ranking, GraphRAG, Self-RAG, and RAG-versus-fine-tuning trade-offs.
• ✓An AI Agents and Agentic Systems section covering agent memory, the ReAct and Plan-and-Execute patterns, tool use and function calling, multi-agent systems, and the Model Context Protocol.
• ✓Scenario-style prompts phrased as real production problems, like a RAG system hallucinating despite having the right context or an LLM gaming its reward model after RLHF.
• ✓Newer research topics sitting next to the fundamentals: Recursive Language Models, Diffusion Language Models, and Group Relative Policy Optimization (GRPO) each get their own entry.

Common Questions

Best use cases

• •Skimming the 'Must Know' list (LLM, RAG, MCP, Agent, Fine-tuning, Quantization) as a fast refresher the night before an interview.
• •Working through the LLM Fundamentals section to fill gaps on attention, tokenization, KV cache, or positional encoding before a technical screen.
• •Practicing the scenario-style prompts out loud, like explaining how you'd fix a RAG system that hallucinates despite having the right context.
• •Pairing each heading with its linked Outcome School video or blog post to turn the list into an actual study plan instead of just a glossary.
• •Checking your vocabulary on newer terms like GRPO, RoPE, or Grouped-Query Attention before an AI Solutions Architect or MLOps round.
