It feels unfocused. Application tracking makes sense, but that isn't the same problem as understanding a company's interview process or talking to other applicants about their experience. And frankly, unless you get the entire industry using this for every job application, the community-based features are not going to have meaningful info. Also, the actual problem implied by the title - have I been ghosted - can be answered with static HTML: "If it has been 2 weeks, yes."

So if I were in your shoes, I'd decide what problem I really want to solve, and build an app laser-focused on a solution for that problem. Bring everything else in later, once you know you have PMF for whichever core problem you choose.
