Domande di colloquio per Software Engineer Java presso NTT DATA FA Insurance Systems

Questions are totally about core java J2EE and most of them are quite tricky and can be manageable, but Interviewer even questioned about my db skills and Angular JS Skills

Had two written tests, 1. Technical - Pure Java, 30 questions, 30 minutes 2. Aptitude - Train, Time, Distance, 30 questions, 30 minutes 3. HR Round - Basic questions 4. Managerial Round - Basic questions This took 2 days and each day they wasted 3 to 4 hours of my time. Had to just sit around waiting for HR. And HR walks in past 11:30 but they ask you to come at 09:30.
