As a person looking for a job, overall it is a horrible and broken experience, and somebody has to fix it. This particular idea is about making it easy to find job applications. Specifically, for the tech jobs, the job board market is too fragmented. They are all separate from each other, and the user has to browse/search or set up notifications (which are broken and useless most of the time, too) one by one.
Job postings aggregator website, that pulls or scrapes the other job boards and allows users to browse/search and apply from one place. Could fix broken (irrelevant) notifications problem, as well.
