## Overview

This is an Express API for interview-session booking, with user registration/login, role-based access, company and session management, and booking rules. The main workflow is a user authenticating, browsing sessions, and creating or managing bookings; bookings update session availability. The README provides no architecture details, and company/booking route implementations were not sampled, so their wiring is not asserted.
