AI Job Application Assistant
Learning project in the AI Learning Tracker series. The AI never auto-submits applications.
Parse a job and a CV, explain the match, draft materials, then stop for a human. The AI never applies.
Overview
The AI Job Application Assistant is Project 3-B. It parses a job posting and a CV, runs an explainable hybrid match, drafts application materials, and waits for human review before anything is finalized. FastAPI is the HTTP surface; LangGraph owns the workflow. Evaluation packs score skill recall, score range, stability, and grounding.
Problem
Most “AI apply” demos skip the dangerous part: sending something in your name. I wanted a workflow that can help with matching and drafts, then stop.
What I built
A LangGraph workflow parses inputs, scores overlap with an explainable hybrid matcher, drafts materials grounded in the CV, and inserts a human-in-the-loop review before finalize. Golden packs under app/eval exercise strong match, weak match, domain shift, and alias overlap without requiring a paid LLM.
My contribution
- Built parse → match → draft → human review as a LangGraph workflow.
- Kept application submit off the graph so a person always decides.
- Added an offline evaluation harness with golden packs and grounding checks.

Keeping a Human in the Loop
What HITL actually means — and why asking “which LEPA area?” is not the same thing.
