views.py

This module contains the view functions for handling HTTP requests and rendering
responses in your application.

Each view function corresponds to a specific URL route and performs the necessary
actions to handle the request, process data, and generate a response.

This module is part of the recruitment project and is intended to
provide the main entry points for interacting with the application's functionality.
