Scholastic Senior Java/J2EE Developer interview questions

Interview went around for the first 90 minutes with 3 interviewers. I know i didn't do it well and couldn't get the offer for contractor position. The disgusting part is after spending 90 minutes, my next interviewer was with the Manager. He told me to wait in his office for some time and he'll be back in 45 minutes. I thought maybe he has to run for production issues or important meeting. I stepped out to the lobby after waiting for 15 minutes to get some water and was shocked to see that the Manager was having chat with people. He came back after almost 1 hour and spent only 5 minutes talking about my skills and work experience.
