Cronos Europa interview questions

I had the contact from their client (I held, previously, the same position in the same office under a different agency). after the first interview I was not judged suitable for the position (which I had already successfully filled, as anticipated). following a few calls I was contacted with an economic proposal about 40% lower than the previous contract ( 2050 gross vs previous 3200 gross for the same position). I tried to negotiate, but they didn't move from the offer which I thought wasn't enough.

3 rounds until reach the end of the process: - first round with HR - second round with the client - third round with the line manager Formal interviews with formal questions about qualifications, experiences.
