Cognizant — Interview scheduling through Berribot

I had recieved a message saying this is bertibot on behalf cognizant and subsequently received a call from the same as well. I was asked certain questions and answered them accordingly. I was told i would have an interview with cognizant on the 30th. But, i did not get any call or email from cognizant regarding any interview. So, was this just a spam message or was it indeed for real.
