Discussion on answer by Old_Lamplighter: Is it normal to be rejected with an automatic email far into the interview process?

The amount of focus this answer puts on petty and unreasonable rejection reasons seems a bit misleading given that, while those certainly do happen, most of the time candidates will be rejected for much more reasonable reasons like a lack of technical skills or knowledge, poor interpersonal skills or a lack of motivation. Or maybe you just have experiences mostly dealing with particularly petty people. Although energy can be a reasonable rejection reason, assuming they want a fun workplace. The "leapfrog" reason also seems like a reasonable concern.
