Oxide's process involves submitting writing with various questions about you, what you've done, and what you're looking for in your career. The process of doing so inherently means reflecting on the answers to those questions, and so some people find it a useful exercise.
OK.
But that should be done later in the process. I'd rather an LLM auto-reject my application vs spending 5 hours on a writing exercise.
Think about, I apply to a minimum of 5 jobs per day. If I need to spend 5 hours for each application I'm spending 25 hours a day on job applications. Obviously this isn't possible.
