I was called by the HR and she asked me a few DS terminologies upfront and after that my technical interview date and time was fixed on the call and that too twice, but up until the interview date the HR did not bother to send me the meeting link and after inquiring about it she was upfront arrogant and said there was some issue so she was not able to set up the interview and I need not talk to her in this manner. But at least you should tell the interviewing candidate about it, they don't value other person's time. If there would have been a client call instead of this interview call on the said date and time wouldn't they inform the client that they won't be able to set up the call for that day. A simple email would have been nice.

It was a telephonic interview. The panel was very professional and knowledgeable. HR ( I think junior HR) was polite and profession too but the head HR had an very big attitude and was very unprofessional. She was down right rude and had a put down attitude.
