NexJ Systems QA Analyst interview questions

I am a graduate in math/finance. This is not my major area, so I don't really know how to answer those technical questions like "Why manual testing is more accurate than automated testing", "If you get a new cellphone that is going to be tested, what you are going to test, and how" etc. So I know I didn't do well in the interview. Other non-technical questions are very frequently asked. You guys can google them. I tend to over-prepared those questions and they didn't really ask that many. The whole interview lasted about an hour.
