'I'm an extremely patient person and have never done anything like this before': Interviewer over 45 minutes late for interview, candidate walks out

Sometimes, the games and manipulation start from the interview, with the hiring party pulling ticks, like showing up late, to "test" candidates, claiming to be testing for traits like "loyalty" and "patience" when really they're just looking to see how much of a pushover the candidates are. 

Really, if you're pulling stunts like this, you're probably discouraging the best candidates from working at your company, which you probably think is fine since you're obviously looking for desperate and pliable workers whom you can exploit. But if you doing this to candidates as a genuine mistake, it's time to reassess your interview process and maybe have a backup interview team present just in case you get tied up with something urgent. That way the backup team can conduct the interview and maybe land you some experienced top candidates.
