Cognizant Software Engineer - Java Developer interview questions

Effective interview process that dealt with the ins and outs of the job. Asked tough questions that put my knowledge in Computer Science to the test. Throughout the process there was effective communication from Cognizant.

I got a call from HR about available date for an interview. I joined the interview and interviewer was available already and I introduced myself for a minute. Interview started at 11:45 and considering introduction for a minute. Then after, he asked concepts like OOPS, what is encapsulation, is-a relationship, Java 1.8 features, interface, springboot and microservices questions, I answered almost all questions to the point. Around 15 questions were asked, I answered all considering each answer takes a minute. He winded the discussion within 15 minutes saying you need to improve and cut the call then and there. I felt it as rude. He might have said to answer the questions through examples. I did my part but he was definitely rude. And then HR called and just one sentence, you did not clear the round and cut the call. Even rude. I hate this discussion and would never want to be part of.
