One thing that infuriates me with job interviews is how they will write you off the second you are late. But they sure as hell can be late by as much as they want. And will treat you like shit if they are in a rush, or if they forgot about your scheduled time slot (had this happen with a phone interview that I even proved to the receptionist that I had in fact followed the instructions). They should be required to pay the person being interviewed for each hour (rounded up even if just 15min) wasted or their own lateness.
