Don't join them in Total Unprofessional Behavior, they will just waste your time. It was a Backend intern (NodeJS) role, the interviewer joined late, asked "Tell me about yourself self" and then 2-3 basic JS questions then he received a call and dude ended the 1-hour interview in 5 minutes, and told me HR will get back to you I told all this to HR but next day got rejection mail
