Why do we still use 3 separate tools for resumes, interviews, and career planning?

It felt like I was constantly starting from scratch. That's why I built UsePathly as an all-in-one AI copilot. My question for the Product Hunt community is: What is the most frustrating, disconnected tool/step in the modern job search process for you? Is it the CV/Resume? The confidence building?
