How do extended interviews root out people that are going to later go through some kind of major personal issue or have burnout or have a lack of motivation? Lack of motivation and burnout maybe could be somewhat sussed out in an interview if it was obvious, but the people that I've been around that's happened to (and myself at one point in my career) were completely fine, but I'm skeptical of any interviewer that says they can reliably fish that out.
