I was hired with the promise of one position, and was talked into another one--until the first one was "ready--which basically turned into a contract position. The first position never materialized, and when the contract position ended I was told "you have to find another position or we will have to lay you off." So basically, what was advertised as a full time position turned out to be a dead-end short term contract position (3 months).
I left for a better position, fortunately, but found out through colleagues at the client company that the account manager made disparaging remarks about me after I left. (Although the director of this particular company called me to tell me how grateful she was for my help.)
After I left a friend took a similar agile coaching position with them and was fired three days after starting. This is a consummate professional with an extensive track record.
The company seems to shift ownership every three years or so, sort of a shell game. They have developer farms in Russia and the Ukraine. I'll leave the rest to your imagination.
