Perguntas de entrevista de vagas de Java Developer da empresa Comviva

I was contacted by the HR and the interview was scheduled after 2 weeks. The first round was a Hackerrank technical round that included MCQs and coding problems. The 2nd round was a technical round taken by 2 people. They asked very basic questions and programs and queries. Not complex at all. I answered all the questions in the F2F interview. The Hackerrank round was also easy with basic questions. My coding problem was also correct. All the testcases passed. But still my candidature was rejected. The experience was not pleasant. They have no feedback as to why the rejection.
