Startup Idea: New Graduate Job Database Platform

Startup idea to develop an online platform where big companies can host job vacancies specifically for new graduates, and offers features like email notifications about new job postings to registered users.

I am a Public Health Student who is getting ready to graduate. Like most other college students we all want jobs after we graduate. I believe big companies should run database sites for jobs that are specifically for new graduates. Possibly even an email that is sent out to anyone enrolled in their site in order to know that they have jobs for college specific students. No I have not. i just search jobs online to apply to.
