Quanta Computer Employee interview questions

Applied through a staffing agency and went in to an interview event with about 50 other people to interview one on one. The whole event seemed unprofessional. Interviews were conducted in cafeteria of one of the buildings where workers were still eating lunch. Each interview took about 5 minutes for each person, and they asked everyone to fill out a questionnaire and contact form. Interviewer asked one question and did not seem happy to be there at all. Once all the interviews were done, everyone was escorted out and were told we would be contacted by the end of the day. Later I was called and told that they were still reviewing applications and that they will call me again in two weeks, but I was never called back.
