Hired to do something never discussed during interviews - Anonymous employee UniCredit Group Employee Review

I had a first interview with the HR and the hiring manager during which they told me about an innovative role within a new department, but it seemed they had not clear ideas about the position and explained the job activities without going into details. Then they offered me the job. I requested a second interview to obtain more details and they kept telling me about how they were doing innovation. Unfortunately I trusted them, accepted and turned down a better economical offer hoping to acquire more knowledge and skills. Once joined I realized they hired people without knowing what they would have done. I was assigned to a task never discussed before and completely different from what I expected (and I was not the only new hired in that position). Even after several negative feedbacks about my situation they just made promises but nothing ever changed.
