# Database tables are created on application start. We intentionally do not
# seed any sample data here. Previously a block of code inserted dummy
# job listings whenever the jobs table was empty. In production, jobs
# should only be added by authenticated recruiters via the job posting
# interface. Leaving the seeding logic in place would result in fake
# positions appearing every time the application starts, which is
# undesirable for a live recruitment platform. If your environment
# requires initial data for testing, insert it manually via the
# database or through the new recruiter job posting page.
