Description

SuperCoolJobs is a full-stack application that allows candidates, recruiters, and companies to network and engage in the job application process. Candidates can apply to jobs, recruiters can post jobs, and companies can hire recruiters to post jobs on their behalf. Candidates, in turn, can place job applications, and recruiters are able to place, view, and modify job postings. Finally, companies have the ability to view their recruiters and their job postings.
