Very dangerous to join - Senior Manager Infineon Technologies Employee Review

Seems to allow managers to change mind on people immediately on having someone join. I was hired in the central corporate function and the interview was hasty, I was told to come on my own expense. Just 2 months on joining I was told to find another position within the company or leave in 6 months. No compensation for having shifted countries to take up the offer. The HR was totally absent in the whole procedure and seems to have no power at all. As I learnt, a hasty hiring decision was made expecting a hiring freeze, but then later when there there turned out to be no hiring freeze, the manager wanted to bring in a more suitable candidate by background.
