1st interview: with HR person: usual stuff, he said he didn't know the budget.
2nd interview: HR person and a department manager, asked me to present my exp related to their needs. He said I was what they needed and asked me for my salary needs.
3rd interview: HR person and general Manager, same as 2nd one plus some other tech questions related to the technologies used.
The process took too long, the HR person had all the specific questions to make you feel useless and manipulate you. In the end, I received an offer of ~4500 Eur/Net/Month, which I declined.
