✅ I built a DevOps Interview Buddy AI agent using n8n + Ollama, and the best part is, it’s completely free.
✅ The idea was simple: Can we simulate a real DevOps interview, not a chatbot that throws textbook answers?
✅ So I gave the model a very specific role: A senior DevOps interviewer who evaluates how you think, how you debug, and how you reason about trade-offs, just like a real production interview.
What are we using?
🔹 n8n – a no-code/low-code tool to automate workflows by visually connecting steps
🔹 Ollama – lets you run AI models locally, no paid AI APIs required
🔹 Docker Desktop – to run everything cleanly on your machine
🔹 Gemma 3 – the lightweight open-source language model used for the interview agent
⚠️ This is a basic use case on purpose. The goal is to understand how n8n connects tools and reasoning together.
