IntelliVision Technologies Developer interview questions

Applied through linkedin, received call from HR for first round of interview, scheduled interview was only for 1 hour, the guy which was supposed to take interview joine half hour late and then they extended interview for more than 3 hours from the scheduled time. Second round of 1.5 hours even after answering all the questions rejected Candidate, very poor time management and some silly questions were asked in interview, they are just wasting time and efforts of people, they should understand that Candidate's are there for interview not for interrogation.
