Intralinks Sr. Software Engineer interview questions

All process took a week, the worse interview I had so far! First-round was with a senior team member, talk about my experience, basic OOP concepts, some simple java related questions. Got invited onsite for 4 hours interview .. complete waste of time only one interviewer was really prepared the rest was just asking questions from the resume. There was one interviewer that never ever needed to interview people, the attitude was horrible, never looked at the camera and speaking very quetlly .. asking questions that were asked 20 years ago, to make sure to confuse me and show nothing on my knowledge and experience. The interviewer not offered to ask questions, so I asked anyway... I asked what do you like about working in the company.. the answer was "I not allowed to share this information it compony SECRET" .. REALLY ?!! Don't waste your time
