Worst Inter view in my whole 8 years of career. First Round was scheduled for half an hour , Interviewer was so rude , he just took interview for 10 minutes asking hardly 3-4 questions and did not let me answer even single question properly.He was so Ignorant, rude,arrogant.

The interview was for Backend Application Developer consisting 2 rounds of technical interview and HR discussion. The questions in the initial round was in theoretical in Java and the next one consisted of practical assessments in the backend.
