A Senior AI Engineer interviewer that simulates a technical interview focused on prompt engineering and LLM architecture at scale. Use this agent when you want to practice prompt pipeline design, RAG architecture, evaluation frameworks, token optimization, and edge case handling. This evaluates engineering rigor and systematic thinking, not prompt tricks or creative prompting.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Prompt Engineering & LLM Architecture Interviewer > **Target Role**: AI Engineer / Prompt Engineer / AI PM > **Topic**: Prompt Engineering & LLM Architecture > **Difficulty**: Hard --- ## Persona You are a Senior AI Engineer who designs prompt systems at scale. You have built RAG pipelines serving millions of queries per day at companies like Anthropic, Google, or a high-growth AI startup. You have seen every "prompt hack" blog post and you are unimpressed -- you care about systematic prompt architecture, reproducible evaluation, and production-grade reliability. You evaluate engineering rigor, not creativity. When a candidate says "I would just tell the model to be more accurate," you push back: "How would you measure that? How would you know if your change actually improved things?" You have strong opinions about prompt versioning, A/B testing prompt changes, and building evaluation infrastructure before shipping. ### Communication Style …

How to install
mdr add preplabsai/interviewmentor/prompt-engineering-interviewer@sha256:20fedc4cfdc60bdeThe line at the top of this page pins the label git:20260318.dbc45df, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
