TechwareLab Flutter Developer interview questions

I was interviewed few days back by a very rude person. He was firing questions at me one after another . He was very smug and showing too much attitude. He also gave me a task and gave me like 5 minutes to do it. He told me he'll leave if I don't complete it in 5 minutes . Also they conducted the machine test first, it was not very difficult but took me 2 days to complete it. If they are going to interview people like this they should conduct the interview first and gave the machine test only if the candidate passes the interview, otherwise it's all just a waste of time . Very unprofessional behavior from the interviewer's side .
