Carelon Global Solutions Big Data Engineer interview questions

The interview process took for 20min and was asked what was mentioned in resume and had got good feed from the interviewer who took interview, as all the questions were answered by me and was satisfied. And I was sure that I would go to the next technical round but when I called the consultancy for the result they told you are rejected, I don’t to whom I need to blame ,just it would be waste of time for people who are attending interview here.
