I think it's easier with stump the chump type questions because some artificial filtering. Interviewing and trying to gain real insight into a person is really hard and time consuming... and many people just can't do it/scale it effectively. A sad reality, but I think it's a similar case if you look at startups compared to existing businesses and how they run. Bureaucracy and layers just get built, it's hard to re-create that initial singular purpose. Now this is just adapted to the hiring process.
