Slack interview questions

Don't spend your time with unprofessional interviewer I was reached out by super unprofessional interviewer for the first round, seems that slack are outsourcing the HR with very unprofessional interviewer (RocketPower). I was notice that the interviewer does not have much experience, he was reading some document and fill it out during the conversation. did not ask me to introduce myself and when i tried he cut me off and said: "We dont have time for introduction", which i found very rude. he was not able to answer any question that I asked (work culture and basic company related questions). He just read me the job description from his document Dont waste your time with unprofessional recruiter
