The HR interview was ok. The first techical interview was not that difficult, but the person who interviewed me had less experience than me.
The second interview with manager was also technical (although HR told me that we will talk only about the offer) and it was a disaster. He gave me opinion about my knowledge and tried to minimize everything I knew and increase what I didn't know. And all of that just so he can find excuse for offering me less money than what I asked for.
