Very unprofessional interview process. A HR called me up and set up an interview with a Director which I accepted. The next day, while I was waiting for interview, the HR sent a note saying they wont be going ahead with my profile but did not send any calendar cancellation. I was confused and tried to reach out to the HR via phone and SMS, but she did not respond. As Google calendar still showed my interview slot, I tried to join the zoom interview call. But Zoom said the meeting link was invalid. There is no explanation, no communication and no response from the HR. Easily among the worst interview experiences I have had
