How do you plan on making money? My concern would be that you need to be extremely upfront about what data you're collecting and if you're selling it back to these companies whom the person interviewed with (even if anonymized). This is a <i>very</i> personal exchange between an employee and employer that could have significant impact on employment negotiations. For example, I might not want employer A, knowing that I'm also interviewing with employer B/C/D, unless I choose to use it for negotiation. This could be used to target folks into lower paying jobs if they don't have prospects, multiple offers, etc.<p>I'm not trying to be harsh here or blow up your idea. Maybe it's a totally free app. I'm not sure. But, if you are selling user data, you could be inadvertently increasing companies bargaining power through hidden knowledge of what someone is doing too. If a company uses this added data on me, and gets me to take an offer that's 30k less per year, and I stay there 4 years, that ends up costing me 120k over 4 years (30k*4y) all for using an interview note taking app.
