Adobe interview questions

Interview was scheduled at 9:00 AM, but by the time I get my turn, it was 12:30 PM. The HR and other people came at 11:00 AM. Though the position is for Java/CMS, the interviewer asked so many hypothetical questions which doesn't have right or wrong answer. Interviewer seems to be from other background. Questions asked have no relevancy to the job description they had provided.
