The recruiter was talking a LOT. Barely asked me something relevant and then finally when he decided to do so, he was taking my words and ''twisting'' them, more or less just trying to confirm his assumptions even when they were completely wrong. No matter how many times I tried to explain something the outcome was just stubborn ignorance.
Really really annoying and ignorant interview, I have never had such experience before (never ever I have failed first interview before), really unpleasant. I will think twice before applying for positions in Ariba ever again.
