Applied online. Had a HR phone call at the same day. A week later, I was notified that my profile was shortlisted for interview. Set the interview date a week later. On the interview day, I arrived an hour early. Half an hour before the interview slot, the HR explained that the interview has to be rescheduled and provided no further explanation. I followed up 3 working days later via email only to be told over the phone call that the requirement of the role has changed, and therefore, they are not progressing with my interview.
