The boss gave the impression of being in a hurry during the interview. The answers were very superficial, or they tried to dismiss me with just one or two sentences. Anyone could tell they were not making an effort. If they did not like you, they would adopt a condescending attitude, as if looking down from a position of superiority. If they are not interested in people, why send an interview invitation in the first place?
