Share Agent interview questions and standard answers, offering a one‑stop solution for Agent interviews, backed by senior AI Agent developers from leading tech firms.
The article explains how to assess Retrieval‑Augmented Generation (RAG) projects using the open‑source Ragas framework, detailing four evaluation dimensions and breaking down specific retrieval and generation metrics such as precision, recall, answer correctness, relevance, and faithfulness.
Skills are structured local folders that encapsulate domain‑specific processes, knowledge, and tools for large language models, enabling on‑demand loading, token efficiency, and reusable workflows, and they differ from one‑off prompts by persisting instructions and supporting templates, scripts, and reference materials.
Retrieval‑Augmented Generation (RAG) lets a large language model first fetch relevant documents, turn them into vectors stored in a vector database, and then generate answers based on those retrieved passages, ensuring more accurate and grounded responses for private or domain‑specific queries.
This guide outlines a comprehensive learning roadmap for large‑model application engineers, covering fundamentals such as Transformer architecture and scaling laws, practical API usage, prompt engineering, retrieval‑augmented generation, agent design, engineering best practices, security, observability, cost optimization, and fine‑tuning principles.
The article explains MCP (Model Context Protocol) as a standardized interface for AI agents, detailing its architecture (Host, Client, Server), three core types (Tools, Resources, Prompts), transport options (Stdio and Streamable HTTP), security best practices, and how it differs from function calling.
Loop Engineering replaces manual prompt writing with autonomous AI-driven cycles that automate task initiation, parallel isolation, skill definition, tool integration, sub‑agent delegation, and persistent memory, enabling agents to self‑manage complex workflows across diverse scenarios.
The article outlines four common RAG chunking methods—fixed-length, recursive, semantic, and structure-based—explains their pros and cons, discusses the trade‑off between chunk size, retrieval precision and context completeness, and introduces two advanced techniques, Contextual Retrieval and Late Chunking, with empirical results from Anthropic and Jina AI.
This article explains what Agentic RAG is, contrasts it with ordinary RAG by detailing its dynamic decision‑making, multi‑step retrieval loop, higher cost and latency, and suitable scenarios, and outlines two implementation patterns—single‑agent and multi‑agent—plus a concise interview response.
The article explains why Retrieval‑Augmented Generation (RAG) addresses the static knowledge limitation of large models, contrasts its role of “what to say” with fine‑tuning’s focus on “how to say,” compares costs and performance against long‑context models, and offers a practical hierarchy (Prompt → RAG → LoRA/QLoRA fine‑tuning → Distillation) plus best‑practice combinations.
The article explains that the fundamental distinction between AI Agents and Workflows lies in who holds decision‑making control, outlines common Workflow patterns, describes the step‑by‑step operation of Agents, and provides clear criteria for choosing the appropriate approach in interview scenarios.
