## Overview

This repository is a Spring Boot backend for an AI interview platform. Its tree identifies authentication, resume handling and analysis, persistence, and security components, but the README provides no workflow details and no source excerpts are available. The graph therefore shows these components without inferring calls, data flow, or external integrations.
