Contacted by HR person and first talk. Second they scheduled an interview with a Product person and a Tech person. The Tech person started asking very detailed tech questions, stopping me in the middle of the answers not really listening much, and 20 minutes before the time scheduled for the interview he said he didn't want to waste my time (while his Product colleague could not ask any question or say anything, just looking and not believing what he saw), and ended the interview in a very rude way.
