Doesn't really sound like a nightmare, just your run of the mill clueless goofballs. And averages are averages because in a normal distribution 50% of the observations are below it. It is strangely fun to see through these terrible job situations though, like a morbid fascination.
I wanted to start this as a series. I definitely have much more. Hired under false pretenses, recruiters lying through their teeth until I signed a contract, doing a day's worth of work and being paid WAY below average, and of course, the run of the mill bait and switch where the switch was done days before signing.
