## Overview

Careerin is a PHP job marketplace connecting candidates with employers, with administrator oversight. The main candidate journey is browsing or filtering job listings, opening a posting, and applying; employers create postings and manage applications, while administrators review companies and postings. Candidate and company account management, resume discovery, and role-based mailboxes are additional product branches. The sampled source confirms database-backed listing and application-status operations; other subsystem links reflect the file tree and remain broad because their implementations were not sampled.

Main entry points: [`db.php`](https://github.com/dhananjaysable/careerin/blob/main/db.php) (Application database), [`index.php`](https://github.com/dhananjaysable/careerin/blob/main/index.php) (Job discovery), [`search.php`](https://github.com/dhananjaysable/careerin/blob/main/search.php) (Job search), [`jobs.php`](https://github.com/dhananjaysable/careerin/blob/main/jobs.php) (Job listings)
