Firstly they discussed the required details and scheduled the interview after 2 days. On the day of the interview , just an hour before they cancelled the interview without even mentioning the reason. I tried reaching HR, She didn't picked up my call , then on text I asked her that Today was my interview scheduled but you have cancelled it to which she replied "sorry your application has been rejected". She did not give any clear reason for application rejection. Just at the end of the moment they cancel the interview.
