Cognizant Associate Projects interview questions

It was just one round of theoretical interview and it was pretty easy. Even coding problems were not asked as such. I couldn't answer a couple of questions but still got selected

For 3 yrs exp, I had only 1 round(technical interview) and HR discussion. The interviewee has great knowledge and is directly associated with the ongoing project. The interview got delayed for about a month after I was shortlisted and informed about it on the call.
