1st round interviewee seems to be in a hurry during the interview. He asked me around 25+ questions in just 30 mins. He touched upon java 8, OOPS, core java, spring core, Hibernate, Spring MVC, REST and Spring Boot He didn't allow me time to think upon any of the questions asked. And he sounded a bit rude while asking questions and was trying to fake a British accent during the conversation. 2nd technical discussion was around the core Java only and it lasted for 20 mins only and that is also cleared.
