Not well prepared by employer for interview. They were in a hurry and didn't pay attention to details. Job description was not correct to what they are expecting. Disappointed with interview process

Had the perfect interview but still got rejected. Had a recruiter screen followed by a hiring manager screen. The hiring manager screen was a complete waste of time. It felt I was rejected even before the interview began and the interviewer was walking through the motions. Straightforward questions that any average PM can answer, I could tell she was going to reject me through her body language.
