Verint Java Developer interview questions

Verint apparently needed many developers, so they invited 10 people at once to come in for an evaluation day. They started by showing us what they do security etc, then they handed an exam with about 8 questions, multi threaded questions, design patterns like composite, singleton. and some array question. The exam was about 2.5 hours with a pen and paper. Then they started calling in people for the next process, a personal interview with one of their team leaders. This team leader disqualified some of the exams because the lock implemented wasn't the way he knew.. Once this first interview was over. Another set of interviewers called me in. One was an older person, who seemed to be in the company forever, the second person was a junior developer. Then they asked me to design a logging system. After that they started asking about memory management in Java, and seemed quite fixated on hands on experience with performance tools the role wasn't advertised as a performance role. Memory management tools, are something you learn in a few days and are generally used in performance roles. After that, there was meant to be another interview, they said they'll contact me another time. I didn't hear anything from them. The process took 7 hours of my day. Maybe 1 candidate moved forward and it sounded like he was under military investigation. The Verint Israel attitude was that of a lucrative company which would be like winning the lottery to work at, yet from internal knowledge the place, doesn't have amazing learning perspects for workers and the managers over there are quite rigid. Overall feeling, average company and ordinary people who rate themselves higher than they really are worth.
