Very friendly boss invites me in. We talk, he is very satisfied. Another short talk with his local operations manager or someone like that. He reassures me, he wants to hire me, that would be more than a formality.

Telephone interview with this fellow. It quickly becomes clear: he feels insulted that he has to talk to me.

The conversation was technically easy, personally a nightmare. The dilemma was: it was very likely that there would be no offer, but I couldn't cancel the interview - that would have looked bad to the first boss. I had to politely endure this fellow's disgusting, insulting style.

Of course, as is usual in Germany, he said nothing that could be his real problem with me.

RDBMS experience, which ones, how.
