Details
The author's goal was to create a DevOps interview simulation that goes beyond a typical chatbot with textbook answers. The AI agent is designed to evaluate the user's thought process, debugging skills, and ability to reason about trade-offs, just like a real production interview. The agent is built using n8n, a no-code/low-code tool for automating workflows, Ollama for running AI models locally without paid APIs, and Gemma 3 as the lightweight open-source language model. The author emphasizes that this is a basic use case to demonstrate how n8n can connect various tools and reasoning together.
