Sony Project Manager interview questions

Phone screening followed by 1:1. Was supposed to meet the team for the next round; but the recruiter cancelled the interview 24 hours before the interview mentioning that the team is travelling and will have to reschedule the interview. Asked for future availability but then never replied back post future availability was provided. Tried to follow up with the recruiter and no response from him after 2 attempts. Very unprofessional; If they had hired someone the least that is expected from the recruiter is to pass that information and close the loop. Cancelling the interview 1 day before the interview and never replying back is not the right way to manage the recruitment process.
