Tata Consultancy Services — Interviewer not Showing up for interview

I apologize for the inconvenience, but my interviewer did not show up for my scheduled interview. I had been preparing for this interview for weeks and was looking forward to it, so this was very disappointing.I understand that circumstances are largely out of your control, but I was hoping you could help me understand why the interviewer did not show up. This is a big opportunity for me and I am worried that a bad impression has been left behind.The interviewer who scheduled the interview is Abdul Faiyaz

Mohan Prasad.
