I applied through college or university. The process took 1 week. I interviewed at Cognizant (Perundurai) in Oct 2020
Interview
I have attended the recruitment process on campus. I want to add that, it was a virtual interview which is nothing but video call. I have an interviewer on the other side. I have been asked questions on Data structure, Operating System, OOPS, DBMS and aptitude questions. Other than this, he asked me about Hadoop, but I don't know about it so, I informed the interviewer. Then, they asked three aptitude questions, and I feel so satisfied in answering those questions. I solved it and told the answers confidently. Then, they asked me to explain the logic so, I did it. Then, he asked me some basic questions in DS and networks. My interview was done.
After a month, we have received the results and I got selected.
